Suburban voters angry with Trump threaten GOP’s grip on House

GLEN ELLYN, Ill. — Control of the U.S. House will be decided in America’s next political battleground of aboveground pools, bike trails, and oversized Tudor and Victorian houses full of working professionals like Karrie Sullivan, a Republican voter who cast her primary ballot last week for a Democrat.

In a suburb outside of Chicago, Sullivan is determined to replace her congressman, six-term Rep. Peter J. Roskam (R), whom she has supported in the past. His sin, she said, was his affiliation with President Trump.
