The 3rd District extends from just west of the Loop to the Southwest Suburbs of Chicago. It's been in the Democrat Lipinski Family (Dad-Bill then son Dan) since 1983. It went 55%-40% for Hillary in 2016. Last time an R presidential candidate won the district was Bush I, in 1988. Whoever the R candidate could have been was going to get killed.
But yes, the Illinois Stupid party screwed the pooch on this one...again.
