In the race for the White House, Democrat Hillary Clinton led Republican Donald Trump by 42% to 37% among registered voters. Clinton also led Trump, 45% to 42% among voters who said they are certain to go to the polls in the fall.
In the Senate rematch, Democrat Russ Feingold led Republican U.S. Sen. Ron Johnson by 46% to 42% among registered voters. Feingold's lead narrowed to 48% to 45% among likely voters.
"An apparently close race and inside the margin of error," poll director Charles Franklin said of the Senate race.
Three weeks ago, Clinton held a 10-point lead over Trump among registered voters and a 15-point lead among likely voters. Essentially, the presidential race is close to where it was before the two parties held their national conventions, Franklin said.
