People are reading entirely too much into President Obama's re-election. He and Organizing for America, the Democratic Party, and allied groups simply beat Romney and the Republican National Committee, state parties, and aliied groups at getting out the vote.
The reason Obama was able to do that is not because of policy or growing popular satisfaction with socialism. He convinced people that he was on their team, and they were on his. After that, nothing Romney said made a bit of difference.
