ELECTION 2004: Here's another Opinion Journal article touting Sen. Lieberman as the strongest Democratic candidate durrently in the running. Peter Beinart doesn't say that Lieberman is leading the pack, but he recognizes that the Senator from Connecticut has a lot going for him that the more left-wing, more dovish Democrats don't. I've said this before.
It's standard operating procedure to play to your base in the primaries and then pull towards center for the general election, so it may hurt Lieberman that he's seen as more conservative than any of the other candidates. However, he's also much stronger on defense than the others are, and that attract the more moderate Southern Democrats.
