You may not have noticed, but there are actually some key primaries going on today in a few states -- and the results will be coming in tonight. Two races in particular bear watching:

• In Michigan's 13th District, a safe Dem seat, the scandals facing Mayor Kwame Kilpatrick could end up spilling over and ruining a big name in local politics: His mother, Congresswoman Carolyn Cheeks Kilpatrick, who has staunchly defended her son in the local press.

A recent poll from Michigan firm Epic/MRA shows Kilpatrick just narrowly ahead in a three-way primary: Kilpatrick 33%, former state Rep. Mary Waters 29%, and state Sen. Martha Scott 24%. If Kilpatrick does win, it will only be because of a divided opposition.

• In Kansas' Second District, Republican voters will be picking the nominee to go up against freshman Dem incumbent Nancy Boyda, who is among the most endangered Democrats this cycle. The two choices are right-wing former Rep. Jim Ryun, who Boyda defeated in a big upset in 2006, or the more moderate state treasurer Lynn Jenkins.

This race has become a major battle between the state GOP's moderate and conservative factions, and these things are never pretty. For example, the local chapter of the centrist Republican Main Street Partnership put out a press release attacking Ryun, charging that by aligning himself with the Family Research Council and its head Tony Perkins, Ryun was effectively in league with David Duke and the Ku Klux Klan.

The polls close tonight in both states at the same time: 8 p.m. ET.
