Pollster: GOP incumbents will try to de-emphasize Trump in midterms

Pollster Lee Miringoff said Wednesday that Republican incumbents will try to keep the midterm elections as localized as possible in an effort to combat Democratic candidates who are tying their GOP opponents to President TrumpDonald John TrumpTrump rallies in Nevada amid Supreme Court flurry: 'We're gonna get Brett' Trump: 'Good news' that Obama is campaigning again Trump boosts Heller, hammers 'Wacky Jacky' opponent in Nevada MORE.

"I think the Democrats are certainly going to like to make that a national referendum, and I suspect a lot of Republican incumbents are going to try to keep it localized if possible," Miringoff, director of the Marist Institute for Public Opinion, told Hill.TV's Joe Concha on "What America's Thinking."

He said it's "problematic" for Republicans "when you have someone like Donald Trump in the White House."

Miringoff's comments come as some Democratic lawmakers and candidates increase their calls to impeach Trump.

However, other Democrats have cautioned against taking the impeachment approach, urging candidates to instead focus on constituent needs at the district level.
