Mate are you fair dinkum here? Don’t you know that Politicians whether they be Trump or Clinton etc are not elected, they are selected WE HAVE NO SAY IN IT! Don’t you even question why only two parties win an election every time an election term comes around? It’s one big puppet show the puppet masters bung on to create division between the un woke populas which is most of the world!
There's a fair degree of corruption that goes on, granted. But that's mainly confined to the parties internal politics (republicans, democrats, Liberals, labor).
However on an election level:
Millions are spent on campaigning, advertisements
Gerrymandering is committed in the US
Biased media agencies produce non stop partisan bullshit 24 x 7
Voter surpression is committed in the US
Democrat emails were released at an OPPURTUNE time right before the election
So what I'm saying is that these parties go to a hell of a lot of trouble to make sure they're elected just for a "fixed campaign"
