Sir, you are wasting your time looking at any US president closely.
Instead you should look at Europe. Why? Because when you look outside of the system you've known your whole life, you can actually see it for what it is.
Recently, in Italy, a political party swept the parliament and now holds 109/630 seats. They are called the Five Star Movement. This party was only founded in 2009. And it rose to fame on ... the Internet. Yes, you read that correctly: T H E I N T E R N E T.
Why am I telling you this?
Because that's what an actual democracy looks like. Where people actually have relevance in politics. Where old parties can be defeated.
In America, we are ruled by two century-old parties that control just about every seat from your town's mayor to county government to president of the union.
Two parties. Over 100 years. Total rule. TOTAL.
What, you think because one party competes against the other, that it is actually a functioning democracy? Ha! The Communist Party of China doesn't even hold all the seats in their Congress. Even they have an opposition front.
Speaking of Communism, a higher percentage of the population of East Germany played a role in their ruling Communist Party than Americans play in the American plutocracy.
The illusion of competition between two liberal, totalitarian (I know that sounds like an oxymoron) ruling parties is simply a psychological trick to make it look like something is actually happening in politics other than a complete and utter stranglehold by a plutocratic ruling elite that has controlled America for the past century.
The reason they do this is because they really don't care about dictating to us socially. That is not in the interest of this regime. All they care about is money and maintaining power with it. They really couldn't care less about gay marriage, gun control, or religion. They just use those things to put on a political show that in no way challenges the continuation of their economic rule.
Obama is just a man put in to entertain people. At the end of the day he is a Democrat, just like Clinton, Carter, and all of the other spokesmen for the two-headed plutocracy of finance and corporations. Goldman Sachs poured money into his campaign, just like they did with Bush.
Heck, if you read about the authoring of the US Constitution, you'll find that not every founding father was an idealist anyway. Quite a few wanted a republic for the rich. Basically a plutocracy like we have.
