While Wisconsin voters still have largely unformed opinions about the two Republicans seeking to unseat her, Democratic Sen. Tammy Baldwin's favorability rating is down a few points from this time last year.
Of 800 registered voters surveyed in the latest Marquette University Law School poll, 37 percent said they have a favorable opinion of Baldwin, while 39 percent view her unfavorably. That's down from 40 percent who had a favorable opinion in March 2017.
Most voters — more than 80 percent for each — said they don't know enough about state Sen. Leah Vukmir, R-Brookfield, or Delafield businessman Kevin Nicholson to have an opinion on the candidates who will face each other in the August Republican primary election.
Of those with opinions, 10 percent viewed Vukmir favorably, while 6 percent had unfavorable opinions. Nicholson's favorability ratings were split at 7 percent on each side.
Among 243 voters who said they plan to vote in the Republican primary, 49 percent said they are undecided. Twenty-eight percent said they would vote for Nicholson, while 19 percent said they would vote for Vukmir. The margin of error for those results was +/- 8.2 percentage points.
