• TN-03: Paula Flowers, the former Tennessee Insurance Commissioner, formally announced her candidacy for the Democratic nomination on Thursday. This is a tough district at R+13, but between it being an open seat (as Zach Wamp is running for governor) and Flowers’ statewide profile, we have a shot here.
• IL-13: Last year, businessman Scott Harper held Rep. Judy Biggert to a much closer than expected margin (54-44) without DCCC help, in this once solidly Republican district (which just plunged from R+5 to R+1). Harper filed an exploratory committee on Friday for a rematch. He can probably count on a higher-profile race this time, especially as strong fundraising might encourage the 71-year-old Biggert to think about retirement.
• MI-07: The GOP is still trying to settle on a challenger to freshman Rep. Mark Schauer in this rural Michigan district. Former Rep. Tim Walberg (who lost after one term to Schauer) seems to have dibs on the race, and state GOP chair Saul Anuzis is thinking he’ll do it again, but Walberg says he’s in no hurry to decide. Brad Smith, a lawyer who’s the son of the district’s former Rep. Nick Smith, seems to be taking shape as their fallback option.
• NJ-03: John Culbertson, a wealthy investor who was courted by the New Jersey GOP to run against frosh Democratic Rep. John Adler based on his capacity to self-fund, says he’s not interested in pursuing the race. (J)
• KS-Sen: I’m not exactly sure what Dennis Hastert has at stake in the Kansas Senate primary, but he waded into it today, endorsing Rep. Todd Tiahrt. (Tiahrt is up against another former Hastert colleague, Rep. Jerry Moran, in a moderate/conservative duel; maybe Hastert sees this as a proxy battle over the GOP’s heart-and-soul.)
• Mayors: In Austin’s mayoral election over the weekend, no candidate finished over 50%, but it looks like there may be no contested runoff after all; 2nd-place finisher Brewster McCracken, who trailed fellow city councilor Lee Leffingwell by 20 points on Saturday, said that he’s bowing out of the runoff and conceding. In San Antonio, former city councilor and rising star Julian Castro easily won against eight other challengers.
