I wrote yesterday about Travis Childers, the Democratic candidate for Congress in Mississippi's first Congressional District. Childer's Republican opponent has been airing an ad that points out that Childers has received support from Barack Obama. In what seems a desperate attempt to preserve his general election chances, Childers has cut a stunning new ad:

Childers describes the association with Barack Obama as an attack. Is that what's in store for the likely Democratic presidential candidate from other Democrats in targeted districts? It's going to make for an awfully uncomfortable campaign if Obama gets such negative treatment from the candidates that Democrats are counting on to expand their Congressional majorities.

The special election is May 13.
