While most of the attention in Pennsylvania yesterday was on the battle for the Democratic nomination, the Republicans also held a primary in the Keystone State (as NJLawyer commented in last night’s results thread). The presumptive GOP nominee, John McCain, of course, won, capturing nearly 73 percent of the vote. But what about that other 27 percent? Ron Paul, who has not officially stopped running, picked up 16 percent, while Mike Huckabee, who has dropped out of the race, accounted for a little more than 11 percent of the vote.

Is this a protest vote against McCain, meaning that he still has a lot of work to do to unite his party? It will be interesting to chart this in the few primaries that remain.
