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:
* By next week, a super PAC affiliated with Mitt Romney will have spent more than $700,000 in Michigan in support of the former Massachusetts governor. Recent polls show Romney trailing in the Wolverine State.
* Rick Santorum hasn’t been much of a force when it comes to television advertising, but he has a new spot out today that pushes, oddly enough, an electability line.
* In Massachusetts’ closely watched U.S. Senate race, a new WBUR-MassINC poll shows Elizabeth Warren (D) with a narrow lead over incumbent Sen. Scott Brown (R), 46% to 43%.
* President Obama’s approval rating is up nationally, but just as importantly, it’s improving in key swing states, too.
* Texas Gov. Rick Perry (R) didn’t do too well as a presidential candidate, but he’s “absolutely” interested in trying again in 2016.
* In Indiana, Sen. Dick Lugar (R) is facing a tough primary challenge from state Treasurer Richard Mourdock, and today, the Club For Growth is throwing its weight behind Mourdock.
* Wall Street profits are up, as are the major stock indexes, but the financial services sector still intends to spend heavily in the hopes of defeating Obama in November.
* In Hawaii’s U.S. Senate race, Rep. Mazie Hirono has a 20-point lead in the Democratic primary over former Rep. Ed Case. More importantly, Hirono also leads former Gov. Linda Lingle (R) in a general-election matchup, 57% to 37%.
