Are they?
Most people just want to have a roof over their heads and food on the table. If left to the right, they'd have a hard time doing that.
Used to be, you graduated high school, you joined a union, you were able to make a living wage and start a family.
Today, thanks to the wonders of conservatism, you leave college with a mountain of debt, you end up in a job with no protections, and you maybe put off having a family until your 30's when the Biological clock is ticking down.
I agree, the 47% who keep voting Republican are fucking idiots economically.
