Pollster: 'Swing voters are getting squeezed out of' the campaign process

Pollster Lee Miringoff said Wednesday that swing voters were being squeezed out of the campaign process because candidates are starting to move away from appealing to the middle in favor of reaching out more to their political bases. 

"We've had all of these wave elections. Every two years there's another one, so it speaks to the dysfunction in Washington and the lack of satisfaction that people have around the country, Miringoff, the director of the Marist Institute for Public Opinion, told Hill.TV's Joe Concha on "What America's Thinking."

"What's perhaps unfortunate for the political system is the swings seem to be more on the political extremes lately, particularly with what we've seen in the last couple elections," he continued. "That leaves fewer purple districts and more red and blue districts, and that becomes a different thing for our politics, so people are talking to their base. The swing voters are getting squeezed out of it." 

The number of swing House districts has dropped from 164 districts in 1997 to only 72 swing districts in 2016, according to the non-partisan Cook Political Report.

Cook also found that 78 percent of Democratic-leaning seats became more Democratic during the 2016 election, while 65 percent of Republican-leaning seats grew even more Republican. 

Though the Senate map leans in favor to Republicans ahead of November's midterms, Democrats stand a decent chance of taking back the House, according to a number of political handicappers.

Democrats need to flip 23 seats in November to win back the majority in the lower chamber.
