And, the Repubs can't win UNLESS they are honest about being conservatives, and honestly govern conservatively. While it isn't written in stone as another post stated, it is written in the party PLATFORM. Reagan stated a conservative platform, and stuck to it, and rolled over the Dems. Both Bushes gave lip service to a conservative platform. Bush I flamed out by parting from his campaign promises in his first term, Bush II waited to his second term to let on that he didn't care about the platform. Note that he only squeaked by in both elections, and did his level best to keep current RINOs in place.
The ones causing the ruckus are those who are trying to hold the Repubs to their platform, which won before, rather than shift to Clinton-lite, which barely squeaks by even doofus candidates like Gore and Kerry.
It's not that Bush 43 doesn't give a damn about Conservatism or the party platform, it's that Bush 43 has his own brand of Conservatism.
The Democrats don't like it because they've spent 60 years just talking about it, while President Bush turned it around into bold action and actually has accomplished what the Democrats spent 60 years flapping their gums about.
Further, you're not crazy about it, because you spend all your time drawing comparisons between Reagan and Bush 43.
In all due respect to The Great One, Reagan fell short of the mark in many areas both domestically and internationally. In many areas, Bush is not like Reagan, although he has excelled in certain areas where Reagan fell short of the mark.
Each one has had their faults.
