Democratic presidential candidate Sen. Bernie Sanders of Vermont currently holds an 8 point lead over Democratic rival Hillary Clinton in Wisconsin, according to a new Emerson College Polling Society poll.
The poll, taken from March 30 to April 3, showed Sanders with 51 percent support in the state, while Clinton had 43 percent. In mid-March, the same poll had Sanders behind Clinton 44 to 50 percent. Both Clinton and Sanders have high favorability ratings among Democratic voters in the state, with Sanders at 83 percent and Clinton at 70 percent.
On the Republican side of the race, Sen. Ted Cruz of Texas leads businessman Donald Trump 40 percent to 35 percent, with Gov. John Kasich of Ohio in third at 21 percent.
Clinton recently criticized Sanders while campaigning in Wisconsin, suggesting that he hasn't been a registered Democrat and that she has been for nearly all her life.
"I am also a Democrat and have been a proud Democrat all my adult life," Clinton said, CNN reported. "And I think that is kind of important if we are selecting someone to be the Democratic nominee of the Democratic Party."
Clinton was raised in a Republican household and became a Democrat shortly after starting at Wellesley College in 1965. Sanders has reportedly never been a registered Democrat and is just one of two independents in the Senate.
"I am not a Democrat and have no intention of becoming one," he said in 1988 while he was mayor of Burlington, Vermont.
Clinton also subtly jabbed at Sanders' plan for a government-run health care system as well as free tuition for public colleges.
"It shouldn’t be enough that people just make promises that are going to be really hard or impossible to keep," she said, according to The Wall Street Journal. "I have watched how we make progress in America, and once you finish venting your anger, then you’ve got to elect people who can get things done."
At her Wisconsin rally, Clinton also criticized Trump.
"When he says, ‘Keep Muslims out of America’ -- a country like ours founded on religious liberty -- when he … insults NATO and our Asian allies by saying, basically, we’re going to walk away, he’s putting at risk the coalition of nations we need to defeat ISIS. He’s basically making our situation worse and more dangerous around the world," she said, The Wall Street Journal reported.
