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.
