WASHINGTON — Michele Bachmann's moment came and went. Chris Christie was a no-show. Rick Perry faded. And now folks are waiting for the Herman Cain boomlet to go bust.
Political observers are beginning to wonder if Republican voters may be done speed-dating and ready to go steady with Mitt Romney.
Rick Santorum, Newt Gingrich and other what-about-me candidates are hoping that Republican voters still may be willing to check out someone else in the GOP presidential race.
That's what motivates candidates who are polling in the single digits to head out the door each day to yet another town hall, Rotary club or fundraiser.
Romney, meanwhile, has been gaining in favorability ratings. But he still doesn't generate much enthusiasm among GOP voters.
