Coral, one of the top British bookmakers, made the Democratic senator from California its early favorite, putting the odds of her winning the Democratic Party nomination at 5-1.

Democratic Rep. Beto O’Rourke, who was narrowly defeated by Republican Sen. Ted Cruz for the US Senate seat in Texas during Tuesday’s midterm elections, followed close behind at 6-1 odds.
