The problem I with the candidates (pretty much all of them, regardless of Party affiliation), is that neither party will hold up someone 'worthy' of the job.
[belief] Anyone worthy/deserving/capable of the job would be either unelectable due to personal beliefs or past decisions (who really cares about how they voted on an issue 30 years ago before they "grew up"), or they are not willing to subject themselves or families to the constant spotlight that they will have to endure on the campaign trail. [/belief]
Santorum is a pretty smart guy = unelectable
Bachman = uhh, probably nuts (kinda easy on the eyes though)
Ron Paul = another smart dude + old = unelectable
etc, and so on....
[opinion] Obama won because of Oprah Winfrey, before she endorsed him, his campaign was going nowhere. I also thought the press went really easy on him, now I'm not a Hillary Clinton fan, but the election was hers to lose, and she lost it. The economy was headed downward, and the Republican party was in power. Therefore, blame the Republicans and vote Democrat. Now the situation hasn't changed, the economy in many respects is worse, unemployment is high, and the Democrats are in power. But a fractured Republican party can't get past the internal squabbles to put forth a united front, and Obama will wind up winning again [/opinion]
Back to Christie as a candidate, I'm all for shaking up the current crop of candidates. Cull the pack of the people who have NO chance, and let the political heavies start battle.
