Sorry if the blogging has been a bit erratic today, but I learned of a death in my family this morning, and have been spending some time making travel arrangements from California to Georgia for tomorrow. Tomorrow afternoon and Thursday, Jesse Singal, who excelled in a weekend guest blogging gig recently, will be filling in.

In any event, here are today’s leftovers:

* Maine Sen. Olympia Snowe surprised just about everyone by announcing today that she’s decided not to seek re-election this year. With her departs about half of what’s left of the moderate wing of the Republican Senate Caucus.

* Mitt Romney spends last day of campaigning in MI blasting Rick Santorum for robocalls to Democrats, accusing him of trying to steal the election. However it affects voters, it certainly serves as a nice pre-spin in case Mitt loses.

* Chris Cillizza runs down counties to watch as MI returns come in.

* Dow closes above 13,000 for first time since May 2008. Thanks again, Democrats!

* Peter Manseau explains the “Americanist Heresy” and its relevance to U.S. Catholic disputes today.

* And at College Guide, Daniel Luzer suggests Newt Gingrich agrees with the President’s remarks about access to higher education because, unlike Rick Santorum, he actually read them.

Polls close at 8:00 p.m. in most of Michigan (other than the western-most portions of the Upper Peninsula in the Central Time Zone), and at 9:00 EST in Arizona. I’ll have a full report on the results first thing tomorrow.

Selah.
