Former Vice President Joe Biden is jumping into a crowded Democratic presidential primary as President Trump gets ready for a campaign rally in Green Bay Saturday.
Wisconsin is turning into a must-win state for both sides.
President Trump is returning to battleground Wisconsin, but the political landscape has changed since his historic, and narrow, win in 2016.
"We believe Wisconsin is a Trump state, not a Republican state," said Kayleigh McEnany, national press secretary of President Trump's 2020 campaign.
Two years later, Wisconsin Democrats went five for five in statewide races.
"In terms of 2018 and the midterms, important to note President Trump's name was not written at the top of the ballot," said McEnany. "That makes a big difference in a bunch of these states, Wisconsin, Pennsylvania, Michigan."
"Well the president did come to campaign for Gov. Walker who ended up losing in a close election. What do you mean by 'Wisconsin is a Trump state?'" asked TODAY'S TMJ4's Charles Benson.
"It's a Trump state because President Trump, since Reagan, is the only Republican on the presidential level to have won it," said McEnany.
"I think what we are going to do here is going to enable us not only win in Wisconsin, but win in states across America," said DNC Chairman Tom Perez.
Perez was in Milwaukee this week as the Democrats prepare for their national convention at Fiserv Forum in 2020.
"History can, and will, I believe, record the important role of Milwaukee during one of the handful of inflection points in our nation's centuries-long journey to form a more perfect union," said Perez.
Despite a crowded Democratic presidential field, Perez says all the candidates are united on an issue that will dominate the 2020 campaign.
"What they all have in common is that they all want to make sure everybody has access to healthcare," said Perez. "They believe healthcare is a right for all - not a privilege for a few."
McEnany expects the Trump campaign to take his healthcare record to voters.
"The fact that premiums for the first year since Obamacare passed - premiums in the exchanges are not going up this year, that's because of President Trump's free market policies, like opening up access to short term plans," she said.
