There is also an agreement the GOP made with the Democrats back in the 1970s not to investigate possible voter fraud in heavily minority districts and precincts, which could be construed by some as minority vote suppression, I suppose.
It was a dumb agreement, because by investigating fraud in heavily minority districts, the GOP would actually be trying to PROTECT valid votes by minority persons. They should tear it up.
