The alerts are already arriving. Hillary Clinton has won Pennsylvania. The victory is not an overwhelming, but it is sound.  Unofficial AP numbers at 9:51 p.m. ET show Clinton leading 55 to 45 percent. This trend among Republicans was reported by the Boston Globe last month:

Spurred by conservative talk radio, GOP voters who say they would never back Clinton in a general election are voting for her now for strategic reasons: Some want to prolong her bitter nomination battle with Barack Obama, others believe she would be easier to beat than Obama in the fall, or they simply want to register objections to Obama.

There are numerous reports of Republicans crossing party lines in Pennsylvania, a process which is a bit more involved in the Keystone state. Republicans must officially changing registration to the Democratic Party to take a Democratic ballot in the primary.

Democratic superdelegates need to keep this in mind as we get closer to the convention. These numbers are significant and warrant consideration. According to the Boston Globe, “About 100,000 GOP loyalists voted for her in Ohio, 119,000 in Texas, and about 38,000 in Mississippi, exit polls show.”

Sources in Pittsburgh report watching media interviews with PA Republicans letting everyone in on the game plan.

How many Republicans changed parties in Pennsylvania for the primary? We’ll learn that soon. But I would certainly not award Senator Clinton the nomination based on the wishes of Republicans.
