This question comes up all the time. It is taken on today by James Carville and Mark Penn in a Washington Post Editorial.

Have A Look:

We don't know if Hillary is going to run for president, but as advisers who have worked on the only two successful Democratic presidential campaigns in the past couple of decades, we know that if she does run, she can win that race, too.

Why? First, because strength matters. Our problems as a party are less ideological than anatomical: Our candidates have been made to look like they have no backbone. But the latest Post-ABC News poll shows that 68 percent of Americans describe Hillary Clinton as a strong leader. That comes after years of her being in the national crossfire. People know that Hillary has strong convictions, even if they don't always agree with her. They also know that she's tough enough to handle the viciousness of a national campaign and the challenges of the presidency itself.

One thing we know about Clinton campaigns: Nobody gets Swift Boated.

I am never myself sure about Hillary. I am confident she would do a really excellent job. I guess I wonder about everyone having an opinion about her. It is a positive because there is less to fear and you know what you are getting but negative because it could really just leave her stuck. I always want someone that trancends the past and someone like her may not. I need to see a lot more of people like Mark Warner before I can give an honest answer. But this piece is interesting and sure aleviates many Hillary doubts.
