I never inferred you did. I know you're smarter than that.
I'm simply stating that you WON'T be given the choice as anyone who will come forward will be stomped on by those who have an investment in the incumbent remaining. Plus, it would look like the candidate wasn't a team player going up against the already in power. But bottom line, you won't be given a choice within the realm of the "party" during the primary.
Plus could you imagine what a primary would do if someone took him on and hit him on the issues we see posed here everyday (some have even been banned for it. Even El Rushbo would probably be at least put in time out periodically with his analysis of certain White House events and issues supported.
Any reasonable candidate would have plenty to run against the president.
But sadly, in the party, you won't be given a choice come primary time.
The so-called "conservative" complaints against Bush all involve variations on the theme of either "spending too much" (mislabeled as "socialism" by the real hacks), signing a so-called "unconstitutional" Campaign Finance Reform bill, or not militarizing our border with Mexico to shoot illegals on sight.
Those aren't "conservative" issues so much as they are all themes of various levels of paranoid xenophobia and misguided interpretations of what precisely is and is not Constitutional (e.g. the Patriot Act is constitutional, and no one to date has shown a single sentence of its actual legal text that exceeds constitutional authority and mandates).
But that point aside, those certainly aren't positions that are even remotely popular. Of course, if your goal is to tear down the Republican Party for the next 8 years, while allowing Democrats to put into office for LIFE their choices of federal judges over that same time span, then such extremist positions are the ideal things to advocate.
