Friday's campaign round-up

Today's installment of campaign-related news items that won't necessarily generate a post of their own, but may be of interest to political observers:
* Former Massachusetts Sen. Scott Brown (R) has reportedly begun looking for campaign staffers in advance of a Senate campaign in New Hampshire. Reports suggest he'll kick off an exploratory committee any day now.
* In Arizona, Republican congressional candidate Jim Brown wrote a Facebook item this week comparing social-insurance programs to slavery. "It is my sincere belief that over entitlements are a means of em- slaving [sic] the people by robbing opportunity while taking care of basic needs," Brown said. He apologized yesterday.
* The Republican National Committee is starting to take Colorado far more seriously, "hiring 11 new field workers, as well as a director of Hispanic outreach and two additional Hispanic field staffers." The state is home to U.S. Senate and gubernatorial races this year.
* In Iowa, the latest Quinnipiac poll shows Rep. Bruce Braley (D) with double-digit leads in this year's Senate race, despite President Obama's sagging popularity in the state.
* Following her narrow defeat this week, Alex Sink (D) is "keeping an open mind" about a rematch against Rep. David Jolly (R) in Florida later this year.
* In Michigan, Rep. Justin Amash (R), generally seen as one of the more libertarian minded members of his party, is facing a primary challenger criticizing him for not being conservative enough on social issues.
* And in Idaho, Rep. Mike Simpson (R) has launched his first television ad of 2014. He's facing a Tea Party primary challenger, Bryan Smith, who's backed by the Senate Conservatives Fund and the Club for Growth.
