Pollster: Keep an eye on upper midwest in the midterms

Pollster Dan Cox said on Thursday that midterm races in the upper midwestern states are ones to keep an eye on in November.

"There's a region that I'm particularly interested in, which is sort of the Great Lakes region, where we saw a lot of working-class voters switch from Obama in 2012 to Trump in 2016, and seeing if they come out, and if they do, do they support Democratic candidates. There's a whole bunch of competitive seats out there," Cox told Hill.TV's Joe Concha on "What America's Thinking." 

"That region will be incredibly important," he added. 

Among the races taking place in the region is Wisconsin Gov. Scott Walker's (R) reelection bid where he is slated to face off against Democrat Tony Evers.
