Five days later, on May 17, 2017, Baldwin made this declaration on Twitter:
Voter turnout in 2016 was reduced by approx. 200,000 votes because of WI’s photo ID laws.
But on a claim closer to Baldwin’s, we rated False tweets that said "300,000 voters were turned away" by Wisconsin’s voter ID law in the 2016 presidential election. A federal judge had determined that some 300,000 registered voters lacked the necessary ID to vote, but there was no evidence that anywhere near that number of people were turned away from the polls.
What about Baldwin’s claim?
