Why do so many Americans elect these corrupt Republicans into office?

I think your talking points are false, but whatever. 77% of the US is Christian and only blue dog democrats care about that torch. Only 20% of the US identifies themselves as liberal, and it's been that way for decades. So you have an uphill battle every election. I won't argue all your points but suffice to say that 50% of citizens pay no taxes beyond sales tax and people making less than $100k generally don't hire employees.
