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:
* On a related note, Santorum and his newly-filled coffers will contest the upcoming Republican primary in Michigan, where Mitt Romney, a Michigan native, is generally expected to do quite well.
* Romney, meanwhile, hopes to lock down a win in Maine, and his campaign has bought cable airtime on the state, broadcasting commercials for Maine's Fox News viewers.
* How many counties did Romney win in Missouri's doesn't-really-count primary this week? Zero.
* The Koch brothers' Americans for Prosperity has decided to sink at least $700,000 into ads in support of Gov. Scott Walker's (R) recall election in Wisconsin.
* The U.S. Chamber of Commerce, meanwhile, is poised to spend $10 million to boost Republican candidates in eight Senate races and 12 House races.
* Ron Barber, a top aide to former Rep. Gabrielle Giffords (D), now appears likely to run for her U.S. House seat in Arizona. Barber, who was injured during last year's shooting in Tucson, will have Giffords' support.
* Also in Arizona, Rep. Ben Quayle (R) will seek another term, but as a result of redistricting, he'll have to run against fellow GOP freshman Rep. Dave Schweikert in a primary.
