Affiliate Marketing Secrets

For a while now I’ve come across people who identify themselves as independent voters. Either they’ve always been independent or were once affiliated to Democrats or Republicans. I’ve heard a good number of them call-in on C-Span’s Washington Journal(call-in show to discuss pol. topics). They usually state Obama “promised this and that or he hasn’t done enough”.
This particular argument confuses me because it sounds like they believe the US is a monarchy, that the President has the sole authority on laws and decisions. Did they forget about the Senate and House? The President can have the intentions of doing something but if he doesn’t have the votes it isn’t going to happen, right?
