I have no evidence of this. BUT, isn't it a little bit coincidental that the day after the "race card" comment people show up at Obama's Town Hall meeting heckling him on racial issues? Someone needs to check into the authenticity of these people, and see if they were a plant paid off by Rove's clowns (clones) who are now running the McCain campaign.
Looks like a duck, quacks like a duck...
The dirty tricks have begun and Obama has to come up with faster, better, smarter, more memorable ways to address them or they will become MSM fodder for taking down Obama just like windsurfing and Swift Boats. And expect more, and worse.
