Dean Phillips, the Democrat trying to oust Republican Erik Paulsen from his Minneapolis-area House seat, blasts the incumbent for having "voted 98 percent of the time with Donald Trump." Jennifer Wexton makes an identical charge against Barbara Comstock in their northern Virginia race - she calls her "Barbara Trumpstock." California Republican congressmen Mimi Walters, from Orange County, and David Valadao, from the San Joaquin Valley, have taken the same hit from their opponents. Ads against Peter Roskam have zinged him over his pro-Trump votes twice.
The data on how much each congressman has voted with Trump comes from the website FiveThirtyEight.
