That has absolutely zero to do with the rich getting richer, and the poor getting poorer. The wealthy, other than religious leaders, do not get rich off of donations.
True, but republican politicians become wealthy by pandering to evangelical fundamentalists who put them in office where they become the beneficiaries of the wealthy lobbyists.
And Democrats remain poor.
How many Dem politicians pander shamelessly to the evangelical fundamentalists in order to be elected?
Not very many since they are pandering to Gays, Atheists, and Wall Street fat cats for their votes and funding.
