Evidently the good Reverend has taken offense to some of the comments made by Obama the last couple of months:
I have had reservations about putting this up. But I can't pass it up. I have never been a fan of this open mic thing. I didn't really like it when it happened to Bush either. But this could have some negative effect this November. A lot of polls show Obama getting unbelievable numbers among black voters. Rev. Jackson has a lot of pull with these voters, deserved or not.
