"The rally doesn't even start for hours, but it feels like a Republican Woodstock." — my mom, calling from Yardley, PA, a swing area. — Robert Costa (@costareports) November 4, 2012

Traffic backup at Edgewood Shopping Cntr, 1.5 miles to Romney's rally at Shady Brook Farm, Yardley, PA #election2012 — abramgertner (@itabramg) November 4, 2012

The rally isn’t scheduled to begin until 5:30 pm ET, but tens of thousands of Pennsylvanians have already descended on Bucks County, Pa., to show their support for Republican presidential candidate Mitt Romney. The Pa. rally comes on the heels of a massive rally in Cleveland just hours ago.

How big is the crowd? No official figures yet, but some Twitter users say at least 25,000:

Republicans say they passed out just under 34,000 tix for the Bucks County rally. There'll be no-shows, but there's a huge crowd here — tomfitzgerald (@tomfitzgerald) November 4, 2012

Twitchy will let you know as soon as we hear something more definitive. In the meantime, just take a look at these photos.
