A new poll finds President Biden marginally ahead of Donald Trump in Wisconsin. For the first time in six waves of polling by Bloomberg News, President Biden now leads Donald Trump in Wisconsin, but every so slightly—46 to 45 percent.

Biden had trailed Trump by 4 points last month. Biden and Trump are even in Michigan and Pennsylvania, where Trump had a six-point lead in February.

Trump continues to lead Biden in Arizona, Georgia, Nevada, and North Carolina, although the president has gained some distance. About five-thousand registered voters were surveyed for the poll, which has a three-percent margin of error.
