Well, the elections are always rigged! (Because of money)
The only reason people suddenly care is because Trump was the one who took advantage this time round.
Everyone wants to complain about Trump, but i hardly see anyone complaining about the buy a vote system America steadfastly REFUSES to fix.
As for people voting for Trump... my theory is this... people simply got tired of *political correctness* - got tired of being told what they should think and say, got tired of feeling like they dont have a voice.
