Vice President Kamala Harris leads former President Donald J. Trump in Michigan by 50-46 percent, according to the latest poll by the New York Times and Siena College. Harris leads by the same margin in the swing states of Wisconsin and Pennsylvania.
The margin of sampling error for the Michigan poll is plus or minus 4.8 points. For Pennsylvania, it is plus or minus 4.2 points. For Wisconsin, it is plus or minus 4.3 points.
The surveys were conducted from Aug. 5 to 9, according to the Times, which writes:
The polls, some of the first high-quality surveys in those states since Mr. Biden announced he would no longer run for re-election, come after nearly a year of surveys that showed either a tied contest or a slight lead for Mr. Trump over Mr. Biden.
While the reshaped race is still in its volatile early weeks, Democrats are now in a notably stronger position in these three battleground states that have long been key to the party’s victories — or defeats. Still, the results show vulnerabilities for Ms. Harris. Voters prefer Mr. Trump when it comes to whom they trust to handle the economy and immigration, issues that remain central to the presidential race.
