Mail-in voting and progressive wins shake up Wisconsin politics.

Republicans in Wisconsin are facing a financial and get-out-the-vote disadvantage due to their lack of mail-in voting strategy, which has been embraced by the Democratic Party. At least 435,000 people voted early, either by mail or in-person, giving a big head start to the Democrats before polls even opened on Tuesday. Some Republicans are renewing calls for a change in strategy, but the resistance from some voters and party operatives is tough to overcome. Democrats credit their robust early vote program as one of their keys to success.
