Results are in from four state primaries held on Tuesday, some in districts newly redrawn ahead of the 2012 congressional elections. Elections in Michigan, Missouri and Washington were generally seen as positive for Democrats, as Democratically preferred candidates from both parties took key victories. In Kansas, right-wing candidates for state senate made major gains in the Republican primaries, ousting at least seven incumbent senators and paving the way for the state senate to shift further to the right. In Missouri’s primary, tea party conservative Todd Akin beat out the wealthy businessman John Brunner in a bid for the seat now held by Democratic Senator Claire McCaskill. Outside groups, including Karl Rove’s Crossroads GPS, have poured as much as $15 million into the state to challenge McCaskill ahead of what’s expected to be one of the most closely watched Senate races of 2012. Meanwhile, in Michigan, longtime Democratic Rep. John Conyers staved off a challenge in a redrawn district, clearing the way for his 25th term.
