Yep. Some impression.
I'll grant campaigning is often limited to stock speeches and sound-bytes. Press releases, campaign position statements on issues can be put on websites pretty cheaply and accessed by most of the voting public, who can, in turn be encouraged to print those statements and pass them on to friends and family. The deeper message can be made readily available, if someone wants to take the time to do it.
That would sure be a better use of time than spewing to people who can't be trusted.
As an aside, part of the whole gig is choosing staffers, and if someone isn't more careful about the company they keep, they won't be effective as every move will be known to the opposition in advance and countered before it happens.
I'm not saying it was ok to malign tea partiers - that pissed me off too. I am saying that his reaction to those few knuckleheads who keep on banging that one useless drum is understandable. If you want to create a case that the guy is a RINO go get the intel and post it.
