A majority of the campaign contributions to Democratic Sen. Tammy Baldwin's reelection campaign are coming from outside of Wisconsin, according to filings.
Baldwin's seat has already attracted millions in outside spending from political action committees that view the first-term Democratic senator as potentially vulnerable during the 2018 elections, with Republicans being the bulk of that spending.
Baldwin's campaign itself is also benefitting from the help of outsiders with nearly 65 percent of all the donations going to Baldwin for Senate, her campaign committee, coming from individuals outside of the Badger State.
During the 2018 election cycle, $1,474,954 million in itemized individual contributions to Baldwin's campaign have come from within Wisconsin while $2,676,353 came from other states.
Californians have been the most generous outside donors to Baldwin's campaign, with individuals from the state giving more than 1,600 contributions for nearly $430,000. New Yorkers have added slightly more than 800 donations for $372,000, while people from Illinois have given 567 contributions totaling $200,000.
Donations coming from other cities and states include: 425 contributions from Washington, D.C. totaling $186,000; 466 donations from Massachusetts for $161,000; 334 from Texas totaling $156,000; and $100,000 from individuals in Pennsylvania and Florida, in addition to tens of thousands from other states.
This is not the first time Baldwin has received a majority of her campaign contributions from outside of the state. During the 2012 election cycle, more than 72 percent of Baldwin's contributions were from outsiders.
Baldwin's campaign has yet to release its year-end figures from 2017. The campaign did not respond to inquiries on its out-of-state donations by press time.
The race for Baldwin's seat is being viewed as a "top race" for the 2018 election cycle and Democrats are reportedly worried about the possibility of Baldwin being upset later this year.
The state went to President Donald Trump during the 2016 election cycle. Additionally, Sen. Ron Johnson (R.), the underdog for months leading up to Election Day, upset former Democratic Sen. Russ Feingold by four percentage points.
Republicans have set their sights on Baldwin and have already poured millions of dollars into the state.
Outside Republican groups have pushed more than $3 million into the state against Baldwin while outside Democratic groups have countered with slightly more than $1 million in support of Baldwin, according to data compiled by the Center for Responsive Politics.
