Clintons and Republicans back together again?

Conservative Talk radio nut jobs such as Rush Limbaugh, Sean Hannity, and others are telling their listeners to cross party lines in the primaries, to vote for Hillary Clinton. The so-called Republican strategy is based on the notion that if Hillary wins the Democratic nomination, then the Republican party will reemerge itself out of the backwoods and once again be a force to be reckoned with. After Tuesday, when Hillary gained some momentum, numerous callers, called into the Conservative Talk radio shows and voiced why they switched. Most were afraid that if Obama were to get the nomination, then all bets are off and the election will be in his favor. Some said his race was a factor( still living in past), others said that he is too liberal. When it came to voting for Hillary, they said that if Hillary gets the node, then their haterd for the Clintons will make a come back and the good-ole days will shine a light upon the party.
Though the Republicans have an up-hill battle, they are out of money and lack a definable positive message that can reinvigorate their base and the American voter. Plus, Obama still leads the delegate count by 106 and the Hillary camp may turn off voters with more attack ads against Obama.
One thing that the Republican party hasn't considered, what if the stars don't align themselves ,in the order, they are hoping they will on election night. This so-called strategy can literally blow up in their faces, if Obama wins the nomination, he will certainly win the election. If Hillary wins both the primary and the election, where does this strategy go next?
The Republicans are putting all their chips in on the roulette table hoping that the little ball lands on their number, which is zero.
