A Jeb Bush ticket would be suicide for the Republicans. G.H.W. Bush was a good man, but was politically a moderate wimp who alienated conservatives. G.W. Bush is also a good man, but is no conservative (he ran as a "uniter, not a divider" and has consistently backed off from conservative positions and kissed up to liberals). Have you ever heard the old saying "Fool me once, shame on you; fool me twice, shame on me"? A third Bush would be "Fool me three times, you must think I'm a complete idiot and I probably am!"
Cheney's heart condition rules him out, and Rice would need some SERIOUS conservative credentials to get past the nominating process.
The best hope for the Republicans is to look at conservative governors (few and far between) as well as senators and representatives. Find someone who energizes the base (Tancredo or Allen, as examples), but also has the killer instinct needed to defeat the Hildebeast. You know that with two Communists on their ticket (Clinton and Obama) the Democraps would pull out all the stops to destroy any GOP candidate. Such a candidate MUST AT ALL COSTS be a TRUE and UNABSHED conservative....and one with enough blood lust to send Hitlery and Osama Obama to a political grave. Another moderate just WILL NOT DO.
My fear is that the blue bloods in the Republican Party will have control and will nominate someone "respectable," and not the blue collar street fighter needed to destroy the Traitor Party once and for all. Bush, Cheney and Rice are all "respectable." "Respectable" gets you beaten when you take on the True Believers....and for all her many faults, Hitlery is a true believer in Marxism, as is Obama. You can't defeat them with "respectability." Be ready to look for someone who is a conservative true believer with the fire in the belly to b*tch slap the Dems back into submission....where they belong!
All of which begs the question: will either President Bush energetically campaign for the candidate you describe?
Given what the demonRATS have to offer, the majority of Americans would rather have an honorable man, with a 'possible' medical condition as long as he has a 'rock solid' VP on the ticket like - Rice. So, the winning ticket is; Cheney/Rice2008
Bob Dole in '08!
