As President Obama spoke this evening in Wisconsin, the crowd began to file out.
Here's video that captures some folks leaving, even as Obama's voice can be heard in the background.
Mike Lowe, a political reporter, also made the observation on Twitter. "Some people --not a lot, but some -- are leaving as the President is speaking," wrote Lowe.
Obama spoke tonight at a rally for Mary Burke, the Democratic gubernatorial candidate in Wisconsin.
Attendees at a recent campaign event President Obama attended in Maryland also left early a couple weeks ago.
