Every time Obama issues another public ultimatum to Congress (before doing what he wants to do anyway) he phrases it in terms like "common sense" or "pragmatic". It's "non-ideological" he insists. The left's ideological agenda just happens to be the common sense pragmatic non-ideological solution.
Obama may be the most radical political figure to occupy the White House, but he is careful to avoid political labels. His leftist allies calculatingly compare him to Reagan or Roosevelt. He's not an ideologue. Just another one of those "Great American Leaders" bent on helping ordinary people.
A big part of the left's latest successes can be attributed to this non-ideological rebranding.
The old left (both old and new) was a political movement that wanted to be understood in terms of its ideology. The post-leftist left wants to be seen as progressive. It emphasizes policies linked to people instead of ideology. The ideology is still there and choking entire university departments to death, but its public face emphasizes an apolitical technocracy of pragmatists and caring social workers.
