FROM CNN's Jack Cafferty:
The Santorum sweep of Missouri, Minnesota, and Colorado once again raises serious questions about why many conservatives can't stomach Mitt Romney.
One, it wasn't even close. And two, Romney failed in places where he was successful four years ago.
Santorum had more than double Romney's support in Missouri.
Romney came in third in Minnesota, a state he won in 2008.
And worst of all for Romney, he was losing Colorado, where he won 60% of the vote last time around.
Writing for the Daily Beast, CNN political contributor Paul Begala points out Romney has more national experience, more staff, more money and "better hair" than Santorum.
Begala described Romney's losses this way, "There's a technical term in political consulting for a performance like that: It's called sucking."
Although Romney is still the GOP's likely nominee, Tuesday’s thumpings will make more people wonder about his electability.
Santorum is now out to convince Republicans that he, not Newt Gingrich, is the strongest conservative challenger to Romney.
And the convergence of recent events is a conservative's dream come true, from the Komen Planned Parenthood uproar to the Proposition 8 ruling in California to President Obama's dust-up with the Catholic Church over birth control.
As for Gingrich, his showing pretty much confirmed that it's over for him.
For Republicans, none of this can be very encouraging. Low turnout in Tuesday’s races suggests Republican voters aren't overly thrilled with any of their choices.
President Obama must be watching all this the way NASCAR fans enjoy a multi-car pileup at the race track.
Here’s my question to you: How does Rick Santorum's sweep change the race?
