So what? They lost comprehensively. The point of politics isn’t to be heard. It’s to win so you can get what you want done done. If being heard led to political change US politics would be a great deal more libertarian. You don’t just need to be heard you need to persuade people to believe what you believe and to vote for you. Money doesn’t do that. It buys you a bigger megaphone but if no one likes the message they hear from you they won’t vote for you. Then you end up like Bloomberg, having spent a ton of money on a Presidential bid that failed utterly.
