Sneaky, sneaky:

For a party that loves to hate the Clintons, Republican voters have cast an awful lot of ballots lately for Senator Hillary Clinton: About 100,000 GOP loyalists voted for her in Ohio, 119,000 in Texas, and about 38,000 in Mississippi, exit polls show.

A sudden change of heart? Hardly.

Since Senator John McCain effectively sewed up the GOP nomination last month, Republicans have begun participating in Democratic primaries specifically to vote for Clinton, a tactic that some voters and local Republican activists think will help their party in November. With every delegate important in the tight Democratic race, this trend could help shape the outcome if it continues in the remaining Democratic primaries open to all voters.

Spurred by conservative talk radio, GOP voters who say they would never back Clinton in a general election are voting for her now for strategic reasons: Some want to prolong her bitter nomination battle with Barack Obama, others believe she would be easier to beat than Obama in the fall, or they simply want to register objections to Obama.

"It's as simple as, I don't think McCain can beat Obama if Obama is the Democratic choice," said Kyle Britt, 49, a Republican-leaning independent from Huntsville, Texas, who voted for Clinton in the March 4 primary. "I do believe Hillary can mobilize enough [anti-Clinton] people to keep her out of office."

I think the last two weeks have shown that Obama is beatable. But more importantly, whatever true percentage of GOP voters are part of the Limbaugh Effect it is a sign that there is excitement in the base.
