I've argued this point with Democrats - they like to believe "their party" is the party of intelligence.
I always just ask them, "which party tries to register people on the welfare lines? which party supports easier voting registration for the less informed? which party wants to restore the vote to felons? which party always carries the uninformed 18-20 year old vote?"
They're college graduates, so they think they and their party are well informed. When they still cling to that, I ask them if they can name the leader of one of the following countries - Canada, the UK, or Mexico?
I haven't met one liberal American college graduate who can answer that challenge on the spot without the internet at their fingertips. But they can always tell you what Jon Stewart says about an issue.
It's the party of hipster dumbasses.
I;ve noticed that the far elft always like to tell each other and themselves how smart they are but once you get them off their bumper sticker slogans and go into more depth then they either clam up or resort to name calling.
The term that was originally used about a century ago and has stood the test of time over the past 100 years to accurately describe people who call themselves “liberals” or “progressives” is “useful idiot”.
That is the term I use. But if “hipster dumbass” works for you, hey, go with it. It gets the point across.
