POLL: Clinton, Trump in tight race in Pennsylvania.

Clinton leads Trump in a matchup by just 1 point, 41 to 40 percent. Libertarian presidential nominee Gary Johnson garners 6 percent support in the poll and Green Party candidate Jill Stein gets 3 percent.

In a head-to-head matchup between both presumptive presidential nominees, Clinton and Trump tie at 44 percent.

But Republicans are more unified around Trump than Democrats are around Clinton, according to the poll, which was conducted before Clinton clinched the nomination.

Hmm. Two thoughts: First, if Trump wants to win Pennsylvania, he’d better saturate Philly with poll watchers. Maybe donate to True The Vote? Also, if I were a smart GOP operative (assuming such exist) I might push Jill Stein in Pennsylvania’s upscale white enclaves, where Bernie supporters might be diverted from Clinton.

What will actually happen: Trump will say something outrageous, people will be outraged, GOP apparat will do nothing useful.
