Recent polls show Democratic Senate candidates in Wisconsin, Pennsylvania, and Michigan losing ground to Republican challengers in narrow races that could determine control of the upper chamber. In the final weeks before the election, the candidates are avoiding associations with Harris and choosing to tout Trump policies in campaign ads that cast them as more moderate candidates, according to the Hill.

In Wisconsin and Pennsylvania, incumbent Democratic senators Tammy Baldwin and Bob Casey are highlighting their work with  Trump. Baldwin, in an ad released last week, touted her advocacy for a Trump-signed bill requiring the use of American steel over Chinese steel in infrastructure projects. Casey’s recent ad highlighted his willingness to defy the Biden administration on fracking and collaborate with Trump to end NAFTA, positioning himself as an "independent."
