WASHINGTON (AP) - It's a good thing the GOP presidential race slows down from here: The candidates are even more tired than the voters. And, boy, does it show.
Mitt Romney scaled back his public schedule this week to get a break. He has slept in his own bed just twice since Christmas.
Rick Santorum's been making the kind of flubs that come with exhaustion. Newt Gingrich got caught sleeping on camera a few weeks back, and looked like he just might topple over.
And then there's Ron Paul. At 76 the oldest candidate in the race, Paul is running a campaign that's a study in ever-so-slow pacing.
Does it matter if the candidates are exhausted? Oh, yeah. That's when they make mistakes, get testy and lose perspective.
