Alinsky's Rules for Radicals: 1

“Power is not only what you have, but what the enemy thinks you have.” Power is derived from 2 main sources – money and people. “Have-Nots” must build power from flesh and blood.

The government has money. (Ours!) The two main political parties have money. The strength that both Donald Trump and Bernie Sanders have comes from people. Oh, they're spending money, but so did Jeb Bush and a lot of others who've dropped out already. They're both affecting people who are unhappy with the status quo and they're getting these people excited about politics.
