I dont understand how the US people and courts allow everything that has been going on. If here in Australia they tried any of the Gerrymandering/voter suppression/political power-plays/outright fraud that has been going on for YEARS in the US, there would be heads rolling. I mean we're pretty apathetic when it comes to politics, but the turning a blind eye to the activities in the US system is just astounding.
