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:
* With Rick Santorum releasing four years of tax returns, won’t Mitt Romney feel a little more pressure to release more than one year? (via Tricia)
* In Michigan, which is quickly becoming an extremely important Republican presidential primary, a new Detroit News poll shows Santorum with a four-point lead over Romney, 34% to 30%.
* A pro-Santorum super PAC hopes to keep the momentum going in the Wolverine State, reserving nearly $700,000 in television time for commercials that are set to begin running tomorrow.
* Romney, meanwhile, is not only outspending Santorum in Michigan by a 29-to-1 ratio, he’s also picked up the support of Gov. Rick Snyder (R).
