The President promised political comity, but vilifies his opponents

He mocks conservative citizens who disagree with him. He vilifies political opponents in Congress, who represent their constituents while his own job approval rating continues to fall. Then there's this, from a Wall Street Journal editorial:

President Obama came to office promising an era of political comity, but even he has had to concede that his first 15 months in office haven't lived up to his campaign hope of transcending partisan divisions. While it takes two to tangle, we think the hyper-polarization owes more than a little to Mr. Obama's own rhetorical habits. More than any President in memory, Mr. Obama has a tendency to vilify his opponents in personal terms and assail their arguments as dishonest, illegitimate or motivated by bad faith.
