I'm not big in american politics (been reading about them to try and have something to say here), but even i understand that people criticising Obama's presidency because he hasn't been able to instantly bring america back on it's feet after the previous president had sex with your country's colon for plenty of years is a bit douchebaggy.
I understand Obama's situation sorta like QU's graph, which i've seen represented in text in many other sites when discussion about that particular topic rises, and this is how i understand his position (and it will probably confuse you guys because i don't know how to say this in english, so sorry if i make any mistakes, but i will use Zero Punctuation-style visual aids), not sure if i'm in the wrong:
This is the state of things as i saw them at the beggining,
Then obama gets elected. Once Bush left, the country's problems didn't just freeze, they just got bigger. When Obama jumped in, the pool was already filled with piss, and it only filled up America, making it sink.
Obama jumped to the piss to try and save America from sinking to the bottom. The water represents the economic crisis and america is under it. When a heavy body hits the liquid it doesn't instantly pop out of it (with a few exceptions), the object's velocity is slowed down by the liquid's density, and then the air within our lungs help our buoyancy.
A president is not a magical entity that once that gets elected, every action of his has immediate consequences, like if it was Midas's Touch or something. During Obama's first period in his presidency, buoyancy hasn’t kicked in as his policies and efforts are the air in Obama’s lungs, and the density of Bush’s piss filled 'Muricah, making it heavy, and so it sank deeper while Obama was working on things, apparently some people believe America sinking during Obama's presidency is his fault.
Obama's actions start to cause an impact, 'Muricah slowly rises from the deep, which brings us to the present day.
If i could vote in your country, i'd vote for Obama because he feels like a better choice to me.
