And there's an excellent example of a reason to never join either party - there're plenty of reasons to be embarrassed with all of them.

For the majority of them both:

They are wildly irresponsible with our money.
They have much too limited a world view, as do we all.
Too many of them have, at best, serious ethics issues.
Too many of them run for office with bluff and bluster, only to work hard to stay in office as long as they're capable of standing up.

Yet, in complete assistance of them, so many of us simply play stupid partisan games like that guy holding the sign, assuming that's really who he is and he really is a fraud.

Frankly, it doesn't matter to me if he particularly is or not - I know there are hundreds of thousands ready to line up to take his place - on every side of the political trampoline.
