The New York Times reports on Sen. Clinton's increasingly narrow path to nomination:
She has to defeat Mr. Obama soundly in Pennsylvania next month to buttress her argument that she holds an advantage in big general election states.
She needs to lead in the total popular vote after the primaries end in June.
And Mrs. Clinton is looking for some development to shake confidence in Mr. Obama so that superdelegates, Democratic Party leaders and elected officials who are free to decide which candidate to support overturn his lead among the pledged delegates from primaries and caucuses.
Part of that strategy has been suggesting the liability of Obama's ties to Rev. Jeremiah Wright:
Mrs. Clinton's advisers said they had spent recent days making the case to wavering superdelegates that Mr. Obama's association with Mr. Wright would doom their party in the general election.
But many people, including Obama supporters, may still have two questions that Senator Obama's speech did not sufficiently answer, at least in my opinion. And, for any Democrat whose priority is to win back the White House in 2008, they need to be answered now -- because, if Senator Obama ends up the party's nominee (I am a supporter of Senator Clinton's) -- for sure Senator McCain will insist they be answered in the fall.
