Virtually everyone expected Tuesday's big political news to come blowing out of Michigan, the big industrial state, where Mitt Romney and Rick Santorum were vying to win that state's GOP presidential primary.

But little Maine managed a national political bombshell of its own with the surprising news that Sen. Olympia Snowe, the 65-year old, three-term moderate Republican senator, won't seek re-election.

From a statement she issued, it appears Washington's partisan bickering just got kind of old for the senator.

Another Tuesday, another critical day for the 2012 Republican presidential contenders.

This time the locations are Michigan, where most polls close at 8 p.m. ET, and Arizona, where voting ends at 9 p.m. ET. The story political junkies are watching closest: Will former Massachusetts Gov. Mitt Romney, a Michigan native, hold off a strong challenge there from former Pennsylvania Sen. Rick Santorum?

Also on the ballots, of course: former House Speaker Newt Gingrich and Rep. Ron Paul, R-Texas.

When he returned from Afghanistan and saw his partner waiting to welcome him home, "four years of pent-up emotion and secret love" just seemed to naturally lead to "what felt like an eternity kiss," Marine Sgt. Brandon Morgan told NPR this afternoon.

If you take a cholesterol-lowering drug called a statin, there's some new safety information you should know about.

For airlines, it ain't easy making a buck. In fact, even a penny is out of reach.

Airlines for America, a trade association for major U.S. carriers, says the industry earned less than half a penny in profits for every $1 of revenue generated during 2011.

The poor financial performance wasn't a fluke. Over the past decade, airlines have lost a collective $50 billion.

On Tuesday, the trade group said something has got to change. Association CEO Nicholas Calio sat down with journalists to explain a new industry push for a "National Airline Policy."
