Democratic presidential candidate Kamala Harris is opening a two-day stay in Wisconsin and Michigan, and Republican candidate Donald Trump will be in Michigan on Thursday as the two candidates grapple for wins in the “blue wall” battleground states, which also include Pennsylvania. Liz Cheney, one of Trump’s fiercest Republican antagonists, will join Harris at a campaign event in Wisconsin aimed at reaching out to moderate voters and rattling the former president. Trump on Thursday will hold a rally in Saginaw County, a bellwether in the center of the state.
