Obama...competent? Really? Versus Romney, who actually had FULLY AVAILABLE documents noting TONS of his various SUCCESSES - even counting the Olympics. When the Republicans had an inkling of an idea of what they would do if elected, Obama's side was just defending - trying to turn the subject away.
You must not have watched the presidential debates. Even the Obama supporters in the room with me (it was a large viewing room) were facepalming at Obama's side due to his butt getting whooped by Romney's side every two seconds.
So you voted for Obama due to his COMPETENCE? Shame on you!
Please, take your red-tinted glasses away- most polls registered a plurality Obama victory in the second and third debates, which is far away from your personal anecdote. And yes, even if you can't understand it, some people (actually, most of the American population according to the latest polls) think Republicans are being even more incompetent with the small share of power they have and feel no desire to give them any more.
You can argue that Obama won his first term thanks to Bush being immensely disliked in the last year of his presidency and the world markets melting down under his watch so people wanted anything but another term of that and the Republicans didn't manage to differentiate themselves from Bush well enough. And the second term can be attributed to Reps moving too much to the right of the general population, which made them an easy target for wealthy-billionaires-who-don't-care-about-you ads (which Romney helped making with his 47% remarks) and a new demographic image the Democrats have fully embraced, winning all ethnic groups except white males- and seeing how whites are declining and half will be females (who also favour Democrats), it's not a wonder they are running with a headstart of over 240 electoral votes in the foreseeable future.
Also consider that the same way you think Obama is an incompetent disgrace, many people think Obama is a good president who has not been able to do anything more because he found an opposition party who didn't want to compromise and instead decided to vote no on everything supported by the President (even if, as Obamacare, it had been designed and supported by Republicans at first), pass all-for-us-nothing-for-you onesided bills in the House and filibuster everything in the Senate. Even Newt Gingrich tried to negotiate and passed a bunch of laws with Clinton after the Shutdown fiasco. Even he looks moderate in comparison now, and the problem is, most Americans would prefer to have a under-average President than give full power to the side that looks increasingly more radical with every passing day. That is, all the people who haven't been alienated firmly into the D side already.
There is a long list, specially in the Senate, of 2010+ Republican candidates who lost theorethically safe seats in red-ish and purple states because they were too extreme for the regular citizen. Maybe that's something worth looking into.
Also, Romneycare (which is Obamacare in Massachussetts) has worked pretty well. Uninsured levels in Oregon and Washington have plummeted in the last weeks. It's a bit too early to decide whether it's a failure or not.
