Unlike mega-rich civilian consumers, political winners are not declared by virtue of having the most toys at the end of the game. The winners of political contests are the ones who have won and scraped up the most mountains of money, enabling them to buy the loudest-possible doomsday-bullhorns that money can buy. The winners are those who can blow out the most voter-eardrums, banging away at the message they choose to endless flay and beat out on their campaign war drums.
So, yes, strictly speaking: We manage to get the best politicians money can buy, via candidates who can bide their time long enough, then make the most media purchases and advertising air-time buys. Money poisons anything and everyone it touches throughout politics, and it's amazing anyone lives long enough to actually serve in office, to live through the poisonous process of simply getting the job.
