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:
* After a brief respite, Rick Santorum is resuming his campaign schedule today, including attending an American Heartland Conversation on Faith, Family and American Values at a bible college in Lancaster.
* According to the Pew Research Center, nearly three-quarters of Republican voters already assume Mitt Romney will be the GOP's presidential nominee.
* In Maine, the latest statewide poll shows former Gov. Angus King (I) with a huge lead in this year's U.S. Senate race.
* Given all of the steps Romney has already taken to alienate Latino voters, I suppose it's not too surprising that his campaign doesn't make a Spanish version of its website available.
* In keeping with institutional traditions and applicable laws, Secretary of State Hillary Rodham Clinton will not be on the campaign trail this fall, and will not attend the Democratic convention in September.
* In Arkansas, Sen. Mark Pryor (D) won't endorse the Republican ticket, but he won't make any efforts to help President Obama's re-election bid, either.
* In Michigan, a new statewide poll shows Romney narrowing the gap against Obama in his birth state, with the president now leading 47% to 43%.
* And in Indiana, conservatives are starting to come out in force in support of state Treasurer Richard Mourdock, who's taking on incumbent Sen. Dick Lugar in a Republican primary. The Club For Growth is airing a new ad, and the National Rifle Association launched this new spot, which hit Indiana's airwaves yesterday. The primary is May 8, four weeks from today.
