GOP says Schultz's testing waters on air; Schultz says he's not running - Michael Calderone - POLITICO.com
Basically, the Republicans raise the argument Schultz exploring the possibility of running on the air is illegal under campaign laws. There is a case to be made, and it's telling that Chris Matthews declined to do that same thing, because of the law.
For the record, I think the laws themselves are wrong, unconstitutional, and antithetical to freedoms of speech, the press, and association.
But it's also true that those who support such campaign laws are far more likely than not to be on Schultz's side of things.
So, it's an interesting story.
