Okay let's start with the positive side: you're right Obama didn't keep his promises. The main reason I wouldn't vote for Obama right now if an election came up is he has only set a hesitant date to withdraw from Iraq and Afghanistan. To me, his main foreign policy campaign was pointing out our mistakes in the past (a correct point-out) yet only exacerbated them by sending more troops in. Makes his nobel peace prize look like bs.
As for everything else, well not good. You can't look at politics between Republican and Democrat. Not only does it show that you have a specific bias that you cater everything to, but it shows a willing fulness to ignorance. Also I don't think you understand what communism is (only the American school text book version). In order for you to ever be considered serious when you talk about these things why not read the communist manifesto to see what communism actually is. I'm not defending it or advocating it as a solution to the world's problems by any means, but I at least understand the concept, why it became as it did, and what Marx was thinking.
Also, America wasn't "founded" on shit. These are just drummed up nationalistic ideals that never really existed. Only because the average American doesn't understand the trials and arguments of the founding fathers (or basic history) do people get away with saying things like..."the founding fathers made this a Christian nation" "the founding fathers sought to have little government". The truth is the founding fathers often contradicted one another. In the most famous case Hamilton and Jefferson. There wasn't a set ideology and the constitution was left vage for many reasons. Hope this helps!
