None of these things are true so Carville may be wrong provided the Republicans grow a pair. If they do fire or bring to justice those responsible then Obama is gone.
The highlight of the comments from the WH so far is Obama admonishing Congress not to "politicize" the IRS investigation. Hutzpah.
The republicans are never going to grow a pair.
The GOP does not believe in conservatism or small government or anything of the sort.
