* In Oregon, Rep. Greg Walden (R) may be a member of the House Republican leadership and chair of the National Republican Campaign Committee, but that didn't stop a local Tea Partier from launching a primary challenge against him.
* In Wyoming, Sen. Mike Enzi (R), facing a primary challenge from Liz Cheney, has rolled out a new ad touting support from Fox News host and former Arkansas Gov. Mike Huckabee (R). In the spot, Huckabee calls Enzi "a principled conservative."
* In a bit of bad form, the National Republican Congressional Committee started polling in former Rep. Bill Young's (R-Fla.) district last night, a day before his funeral. Party officials apologized this morning.
* In Nebraska's open U.S. Senate race, several Republicans are vying to replace retiring Sen. Mike Johanns (R), and this week, the Senate Conservatives Fund endorsed Midland University President Ben Sasse. The news is expected to give Sasse a fundraising boost.
* House Speaker John Boehner's (R) Ohio district is considered a pretty "red" seat, but that hasn't stopped Miami University of Ohio professor Tom Poetter from launching a campaign against the incumbent. Poetter, an education professor, has also directed the university's Partnership Office, which helps the university reach out to the surrounding community.
* Rep. Kerry Bentivolio (R) is already facing a spirited primary in his Michigan district, but if he prevails, he may face former State Department senior adviser Bobby McKenzie (D), who launched a campaign this morning. Other Democrats, including interim Wayne State University Law School Dean Jocelyn Benson, have expressed interest in the race.
* And reflecting on his failed presidential campaign, Herman Cain argued this week that the Devil was responsible for the sexual-harassment claims that helped undermine his campaign. Good to know.
