Period. If he were a Republican, no Democrat would consider him qualified to be President, regardless of where he stands on particular issues.
It's nice that a candidate shares your views. It's even better if the candidate can get elected. Otherwise, you can cuddle up with your shared views after another GOP win.
If Sen. Clinton's electability is a concern--I don't share this concern, but I understand it--there are others in the race now who are more likely to win a general election than Sen. Obama.
Because they're white? No. Because they have accomplishments that qualify them for running the world's largest economy and military and diplomatic forces.
When he ran for President in 1988, Jesse Jackson was more qualified for the office than Sen. Obama is today. Rev. Jackson had 20+ years of political experience. (I voted for Rev. Jackson.)
Apart from his rhetoric and personal narrative, Sen. Obama has nothing to offer America right now. He has the qualifications of someone who was recently only a short-term state Senator.
Sen. Obama and his supporters are worried about Sen. Clinton's honesty? Every time he brings it up, even indirectly, Sen. Clinton should hold up a copy of Sen. Obama's resume.
It would fit in a fortune cookie.
The point: Maybe Sen. Clinton isn't honest. (I don't agree, but I can see why someone would feel this way.) There's serious debate about this. But Sen. Obama is unqualified for the job. There's no debate about that.
If you don't like Sen. Clinton, please find another candidate, but kindly don't stick Democrats with Sen. Obama. Cf. George McGovern 1972.
