No primary in the 5th, 6th, and 7th, Democrat, Republican, Democrat. (Remember, just because there is no primary does not mean there is no election in November.) In the 8th incumbent Rep. Duckworth will be going against Larry Kaifesh, 23 years Marine Corps., Iraq, Afghanistan. Kaifesh's main goal seems to be "Save America", which he looks capable of doing single handedly. From the way Doug Truax's campaign went he might have a hard time getting to Congress however.
Kaifesh is going to have a hard time because the district is drawn in such a way that the Democrat is heavily favored. Also, Duckworth has a pretty good reputation (not entirely deserved, because she hasn't done that much.)
I voted for Duckworth in 2012 because Joe Walsh is a screaming lunatic. (I listen to his radio show on WIND, and frankly, am happy this fool is no longer in Congress.) I could vote for Kaifesh, but I'll watch how the race shapes up. I'd be fine with either one of them in Congress at this point.
