What are the three primary colors?

In the book, the plotline diverges from the real-life 1992 Democratic primary when a surprise candidate, Florida Governor Freddy Picker, makes a late run at the nomination. Picker campaigned by waving a broom and shouting that they'd make a clean sweep. It's not clear which candidate, if any, this is based on, though most political observers believe him to be an amalgam of Jerry Brown and Ross Perot. Picker also shares biographical similarities with former Florida governor, Reubin Askew. Brown stayed in the race, continuing to needle Clinton, even after he no longer had a chance at the nomination, and Perot jumped into the general election campaign in the summer of 1992 as an independent candidate.
