it is pretty entertaining to watch. The way liberals win is by appeal to the base nature of humans. many so-called "conservatives" in power have adopted the same "elites are entitled to rule the world" view, and if they are getting payola for playing along, it is quite tempting.
Said shorter, liberals win because "conservatives" in power are fake too. The "dueling parties" act is a charade, kabuki. The people let it happen. You can blame the mugger for trying to take your stuff, but if you don't fight him, he takes your stuff.
The entire political game is like going to a circus. There are lots of acts to see. We have a ring master, freaks and even clowns.
