@izzythepush,
We view this race from different perspectives:
Virtually no conservative considers Obama competent, and disagrees with most of his policies.
On the other hand, there is certainly objective evidence to suggest that at least Romney, Cain, Huntsman, Perry and Johnson have a record of competent executive experience.
In addition, each one of the candidate advocates more conservative apprecitated policies than Obama.
Gingrich and Santorum have had successful legislative careers and, once again, most of the policies they promote are favored by conservatives.
I don't think Bachmann and Paul have not demonstrated much success (other than in getting elected) during their careers, but they are no less experienced than Obama was when he won the presidency. Yet again, most of their positions resonate with conservatives.
Not one of thee candidates would be my first choice, if I was allowed to make the choice, but you have to play the cards your dealt.
If you believe the current president is an incompetent executive and you ideologically disagree with a great many of his policies, it's not hard to imagine throwing the lever on Election Day for any of these candidates should they obtain the nomination. In a number of cases, you will be crossing your fingers and hoping they surround themselves with first class advisors, but when Obama won, there was very little hope, or reality, around that.
It would take a moderate Democrat with a strong record of executive achievement (I can only imagine a governor; never a legislator, community activist, or professor) but I could see me contemplating voting Democrat. No such Demcrat candidate will be on the ballot in 2012.
I think the Anyone but Romney movement is counter-productive.
There is no guarantee that any of the Republican candidates can beat Obama, but if, for the sake of argument, Romney is the only one who has a chance, then I far prefer that he run than a more stalwart conservative who is sure to be defeated.
Right now, for a number of reasons, the only two Republican candidates who I feel have a very good chance of defeating Obama are Romney and Hunstman. The latter will almost assuredly not win the nomination, and the former very likely will.
Each have a long experience of executive competence, and both are far more conservative than Obama.
