First of all, if you want to "change" everything and therefore you cast your vote for Republicans, all Republicans, and only Republicans, then your logic fails me. What it seems you really should be doing is voting against every incumbent. Logic: get some! It's free! And yes, I also made fun of Democrats who voted for "change" in 2008 (and used it as a campaign slogan) here and here because it sounded just as dumb then.
Secondly, another great way to change Washington? Third-party candidates, my friends. Or, third and fourth and fifth. The Greens and Libertarians come to mind; stop dismissing them and then complaining that Washington is "business as usual."
Finally, when I hear my friends and people on the radio and other random squeaky-wheel strangers talk about how after these past two years they are tired of it all and just need to vote the "ruling" party out, I think back to 2002 and 2004 when we had a murderous administration headed by monsters who were not only profiting from wars they had lied their way into (and which they had plotted from their first days of taking power), but also actively torturing people around the world and who to this day continue to detain, torture and kill thousands illegally, unethically and unconscionably. Then I realize that these crimes were not enough to motivate my friends, people on the radio, and random squeaky-wheel strangers to "change" things and vote those thugs the hell out of D.C., and I am shocked and saddened to see where everyone's priorities lie.
No thanks to anyone in the U.S. "news" media, I might add, for all of the above folly/murder.
Happy election day!
