Yesterday, I was canvassing for Barack Obama in Wausau, Wisconsin when an elderly man brought this flyer into the office. He said it was taped to mailboxes all over his neighborhood. At the bottom, in fine print, is written: Approved and Sponsored by: Barack Hussein Obama II for President, Wausau Chapter. Is this another whisper campaign? It reminded me of eight years ago during the presidential primaries, when dozens of South Carolina radio stations received phone calls from people claiming John McCain had fathered a black child. The story was false, but many believe it helped tank McCain’s candidacy.
