A few $5/$10 million bets by radical billionaires is all it would take. These are bets, not donations. They could win.
$5/$10 million to make it look like their candidate will win? Pocket change for them, and they would reap hundreds of fold that much if she wins.
Ridiculous? Absolutely not.
Probable? Absolutely yes.
