came under withering attack from the rest of the Democratic presidential field last night in a pitched two-hour debate that her opponents used to challenge her candor and electability and to portray her as enabling President Bush to prepare for an invasion of Iran.

At the debate, Clinton appeared to both endorse and oppose Gov. Eliot Spitzer's controversial plan to give driver's licenses to undocumented immigrants.

only Sen. Christopher Dodd said he disagreed. He then pressed Clinton on the issue and argued against the plan, saying: "A license is a privilege, and that ought not to be extended, in my view."

Clinton responded: "Well, I just want to add, I did not say that it should be done, but I certainly recognize why Governor Spitzer is trying to do."

Dodd then quickly interrupted Clinton before she could finish, seizing on the apparent discrepancy. Moderator Tim Russert then tried to elicit an answer on whether she supported the plan or not, but she avoided offering specific support for the plan.

Advisers to Obama told NBC News that Obama reviewed tapes of Bill Clinton's debate performances in his victorious 1992 campaign for clues to how to ratchet up his attacks on [Hillary Clinton] without sacrificing his likeability.
