Mrs. Clinton says she will fight on -- and she's right to do so. We say that not because of Pennsylvania's interest in holding a relevant primary on April 22. Simply put, this fight isn't over.
To be sure, Mrs. Clinton is trailing in the combined totals of delegates and the math looks bad for her chances. Even so, Mr. Obama hasn't clearly won. What we have now is something of a stalemate, one that is likely to harden before it breaks. As Sen. Bob Casey said of the candidate he endorsed Friday, Mr. Obama is "the underdog in our state." Gov. Ed Rendell, who supports Mrs. Clinton, believes the race will tighten.
All of this speaks to the larger picture: It's premature for Mrs. Clinton to quit while the race remains competitive. These calls to step down by Obama supporters are no more realistic than the earlier ones floated by the Clinton camp that Mr. Obama would make a great vice presidential nominee on a "dream ticket."
While Pennsylvania has a late primary, it is not the latest. Among others, the voters in Indiana and North Carolina (May 6), West Virginia (May 13) and Kentucky and Oregon (May 20) will still have to be heard from after Pennsylvanians go to the polls three weeks from today.
As Major League Baseball starts another season, a bit of hardball wisdom from Yogi Berra applies to the Clinton-Obama race: "It ain't over till it's over."
