Losing just one of the Democratic seats in West Virginia, Indiana, North Dakota, Montana and Missouri – all won by Trump in 2016 – could doom any shot of retaking the Senate. “Those five states are clearly the biggest targets for Republicans,” said Geoffrey Skelley, a non-partisan analyst at UVA’s Center for Politics. “There’s two ways to look at the Senate map. It’s really bad for Democrats, but the flip side of this is that this is a perfect year for them to be defending it.”
