There is no doubt: John McCain, the Republican nominee, is like his fellow Republicans, a monster. A corrupt, criminal, murderous, callous son-of-a-bitch who will continue the Republican destruction and sell-off of America while murdering people the world around to enrich themselves. So, most thinking, caring human beings will not vote for him. Of course, 40% of the American public does not fit that description, so he will get at least that percentage of American votes.
Barack Obama, the Democratic nominee, is not a known monster, but that's hardly a reason to vote for him. Since winning the Democratic nomination, he has begun to back away from many of the positions he took when people were voting for him. He is now taking Republican positions on issues like Iraq, the economy, and healthcare, in effect, betraying the people who voted for him in the primaries. He is certainly beginning to look like a monster, call him a maybe-monster.
To the diligent observer it seems that the appearance that there are two major political parties in America is just that, appearance only. The monsters are everywhere.
