Then like Martin said, you should root for Sanders and Trump. Especially Trump. I think Bloomberg will get in the race if it's Trump vs. either Hillary or Sanders. He could make a big enough splash to start a movement for a third party.
As many parties as possible, take the money out, every has a cap on what they spend/donate, best candidate wins.
There is nobody stopping anyone from making other parties. If you cap spending some other super pac or whatever will spend. Plus it's unconstitutional to tell me I can't spend money on getting out whatever message I want, no matter who I am.
I sure hope Bloomberg runs even if hillaryn is nominated. It seems certain he will run if it is Bernie. But Bernie has zero chance.
You should consider moving to N Korea if you want more authoritarian controls. If, for example, A few of us here decided to pool a few million and run anti Hillary ads, we would hope your jackbooted Secret police didn't throw us in the gulag. Free speech is the most important thing. And that includes super pacs organized to support a politician or cause. If you think a candidate is bought, vote against him. I don't care if they are bought, I just want them bought by the right people.
