Democratic presidential candidates ramped up attacks on their top rivals on Sunday as they make their final pitches to voters ahead of Tuesdays New Hampshire primary. 
Fresh off their success in Iowa, Sen. Bernie SandersBernie Sanders Biden says Buttigieg is ‘not a Barack Obama’ on NH campaign trailDemocrats make final pitch at rowdy NH political spectacleIowa Democratic Party reviewing results from 95 precincts following caucusesMORE (I-Vt.) and former South Bend, Ind., Mayor Pete ButtigiegPeter (Pete) Paul Buttigieg Biden says Buttigieg is ‘not a Barack Obama’ on NH campaign trailIowa Democratic Party reviewing results from 95 precincts following caucusesBloomberg meets with Democratic governorsMORE, who both claimed victories in the first-in-the-nation caucuses, took swipes at each other over their campaign financing strategies. 
Sanders, who is running a grassroots campaign, took at shot at Buttigieg over the mayor accepting donations from billionaires. 
Were going to contrast our view with Mayor Buttigiegs, Sanders said on CBSs Face the Nation, about his campaigns plan to emphasize Buttigiegs billionaire donor support. Sanders has already begun to make the argument on the campaign trail, telling supporters in New Hampshire that Buttigieg is the favorite candidate for Wall Street donors. 
Sen. Elizabeth WarrenElizabeth Ann WarrenDemocrats make final pitch at rowdy NH political spectacleIowa Democratic Party reviewing results from 95 precincts following caucusesSunday shows preview: Top tier 2020 Democrats make their case before New Hampshire primaryMORE (D-Mass.), who placed third in Iowa, similarly continued her pitch for her grassroots funded campaign. She pushed back on Buttigiegs argument that it’s important to build the biggest coalition, even if that means accepting billionaire money. 
The coalition of billionaires is not exactly whats going to carry us over the top, Warren said on ABCs This Week. 
Rather than calling out Buttigieg by name, like Sanders has, Warren focused her attack on former New York City Mayor Michael BloombergMichael Rubens BloombergBloomberg meets with Democratic governorsBloomberg wins endorsement from Democrat who flipped Michigan seatBill Maher to Steve Bannon: ‘I wish we had someone on our side as evil as you’MORE. 
Democrats and Republicans get that theyre getting the short end of the stick, and whats the reason for that? Its corruption, she said.  Its a bunch billionaires that make big campaign contributions or reach in their own pockets like Michael Bloomberg does.
Bloomberg is skipping New Hampshire, along with the other first four states, focusing instead on the delegate-rich states that vote on Super Tuesday. The billionaire is self-funding his campaign and not accepting donations. 
Buttigieg continued to defend his campaigns financing, despite the attacks from candidates to his left. 
Bernies pretty rich, and I would happily accept a contribution from him, Buttigieg said Sunday on CNNs State of the Union. 
He added that Democrats need to make sure we bring everybody into this fight, to take on President TrumpDonald John Trump Biden says Buttigieg is ‘not a Barack Obama’ on NH campaign trailDemocrats make final pitch at rowdy NH political spectaclePelosi: Vindman ouster is ‘shameful’MORE and his allies in November. 
Buttigieg also pushed back on an attack from former Vice President Joe BidenJoe Biden Biden says Buttigieg is ‘not a Barack Obama’ on NH campaign trailBloomberg meets with Democratic governorsMayors come to Buttigieg’s defense over Biden adMORE. 
A Biden ad released Saturday hit Buttigieg over his inexperience, juxtaposing his record as mayor with the former vice presidents work in the Obama administration. 
“So many communities look like mine in South Bend. We know we might look small from the perspective of Washington, but to us what’s going on in Washington looks so small or small-minded,” Buttigieg said Sunday on CNN’s “State of the Union” in response to the Biden ad. 
“And communities, whether theyre my size, or rural communities, or even neighborhoods in our biggest cities that feel completely left behind, are frustrated with being made into a punchline by Washington politicians.” 
Buttigieg has made the argument that the party needs an unconventional, outsider perspective, which he claims to possess, in order to take on Trump in November. Hes noted that the party performs best when it nominates a candidate who has had fewer years in Washington politics, including referencing former President Obama. 
Biden, who has been hitting hard on contrasting his and Buttigieg’s backgrounds, told reporters Saturday that Buttigieg is not Barack ObamaBarack Hussein Obama Biden says Buttigieg is ‘not a Barack Obama’ on NH campaign trailBiden rips into Buttigieg over experience in new adThe betrayal of Democratic voters: Many ‘liberals’ need Trump to winMORE. 
“So what has he done?” Biden asked on “This Week.” “Who has he pulled together? Does he know any of the foreign leaders? I mean, Barack Obama was a different story.”
Buttigieg responded on several Sunday Shows, saying that Biden is right. 
Im not, and neither is he, neither is any of us, Buttigieg said on Fox News Sunday. This isnt 2008, this is 2020.
Biden also attacked Sanders over the senators self-identified title as a Democratic Socialist. He said Sanders at the top of the ticket would cause a bigger uphill climb for down ballot candidates in moderate districts. 
You’re going to help somebody in Florida with the label Democratic Socialist? It’s going to go all the way down the line. That’s what’s going to happen. You’re going to win in North Carolina? You’re going to win in Pennsylvania? You’re going to win in those states in the midwest? Biden said on ABCs This Week.
Sanders pushed back on that argument on Sunday, telling CNNs Jake TapperJacob (Jake) Paul TapperGeorge Conway: ‘Verdict of history’ will be on Romney’s sideButtigieg says Democrats must ‘galvanize,’ not ‘polarize’ voters2020 Democratic hopefuls focus on Iowa while making final pitchesMORE his his agenda is precisely the agenda that the overwhelming majority of the American people want. 
Our agenda is the agenda of working-class and middle-class Americans, he said, noting his position on raising the minimum wage, universal healthcare and climate change. 
The candidates’ attacks come as they head into Tuesdays first-in-the-nation primary in New Hampshire. No candidate has ever won the party nomination without placing first or second in either New Hampshire or Iowa, placing additional pressure on Warren and Biden to move into the top two this week.

Biden, who came in fourth in Iowa also defended his prospects, saying on ABC’s “This Week” that “no one has ever won the nomination without being able to get overwhelming support from the African-American community either. So far, no one’s doing that but me.”
Sanders, who won New Hampshire in his 2016 bid, is leading the field at 28 percent, according to a CNN poll released Sunday conducted by the University of New Hampshire. 
Buttigieg pulled ahead of Biden into second place at 21 percent, based on the poll. Bidens support dipped 4 points, placing him in third at 11 percent, based on the poll. Warren is in fourth at 9 percent, according to the poll of 384 likely Democratic primary voters. There is a margin of error of plus or minus 5 percentage points.
