It's amazing and hilariously predictable how liberals will never just admit that maybe their position is not popular. It always has to be that the Republicans cheated, or that the electorate was deceived into voting a certain way.
I doubt I'm going to get more than a "DAMAGE CONTROL XFD" response to this, but... this doesn't contradict with some of the reasons you listed. People who give these reasons don't deny the liberal position is unpopular, they're saying the position is unpopular because the electorate was deceived into thinking conservatism is superior to liberalism or whatever.
