It's not pretty but its politics. Obama was one of the most closely examined Presidents ever. The problem the Republicans had at the time was he was more than careful. He was a constitutional lawyer.
The animosity in the government has pretty much stopped much work of value to be done. Blame whomever you wish but nothing of consequence gets done unless that party enjoys enough of a majority to get past dissenting votes. Not much with regards to bipartisan support as well. In some areas its crippling the function of the government.
