COLUMBUS, OHIO - Now it could get ugly.
Hillary Rodham Clinton's victories in Ohio and Rhode Island aren't enough to turn the tide and overtake Barack Obama, who still leads in delegates needed to win the Democratic presidential nomination.
But her victories were enough to stop his winning streak at 12 and break his momentum. Perhaps more important for the party, Tuesday's results likely ratified her scathing attacks on Obama as a political neophyte who would endanger the country.
She almost certainly can't overtake him in the 11 states left to vote.
However, she can stay in and hope that he falters under her attacks, tough new scrutiny from the news media and more Clinton wins in such states as Pennsylvania -- with its 158 delegates at stake when it votes April 22.
As long as Clinton thinks that her attacks work and suspects that other forces also might be starting to line up against Obama, she'll stay in the race and keep hitting him harder and harder.
Then she could make a new pitch to party insiders such as governors and members of Congress, who hold 795 delegate slots, to give the nomination to her.
