i don't think that's a fair assessment. the entire platform of the GOP from the moment he was elected has been to divide the country to oppose him, regardless of whether he wanted to do good things or bad things. i honestly blame them & the pundits that support them.
when Bush was president, it was "don't speak ill of the president even if you didn't vote for him that's un-American" -- under Obama, it's been "our number one priority is to make Obama a one-term president" even during his second term.
