State Significance

Illinois is a modern Democratic stronghold that hasn't elected a Republican for president since George H.W. Bush in 1988.

It's also the adopted home state of former President Barack Obama, who previously served Illinois in the U.S. Senate. He won Illinois by yawning margins in 2008 and 2012. His former running mate and current Democratic presidential nominee, Joe Biden, is easily expected to carry the state, which Hillary Clinton also did four years ago by 17 points.

Incumbent Sen. Dick Durbin, the Democratic whip, is favored to win a fifth term against four challengers. Similar to other conservative-leaning rural and suburban swaths of the midwest, a cluster of U.S. House seats across downstate Illinois have been Republican-held for decades, but Democrats have a chance to flip a seat in the competitive 13th Congressional District race.
