In Austin, Texas, a homeowner hung an empty folding chair from a tree branch in front of his house and later attached an American flag to it. He reportedly told a Democratic political blogger who said she had concerns, “You can take it and go straight to hell and take Obama with you.”

In Centreville, Va., an empty chair with a sign reading “Nobama” was strung from a tree in or near a park. “In short, this appears to be a crude metaphor for the lynching of President Obama,” wrote the blogger who posted the photo.

The image of an empty chair has been associated with Obama ever since Clint Eastwood’s headline-grabbing, non-conformist speech at the Republican National Convention three weeks ago in Tampa, Fla. The 82-year-old actor-director talked to an empty chair as if the Democratic president were sitting in it, criticizing and mocking the “invisible Obama” for 12 minutes.

“When somebody doesn’t do the job, you’ve got to let them go,” Eastwood said before making a throat-slashing gesture.
