This week we’re going to look at the contest for the Democratic nomination in 2020. At the moment the most liquid market is on Smarkets, with £42,747 traded (compared with £24,749 on Betfair). The current favourite is California senator Kamala Harris, pictured, at 5.9 (16.9%), followed by Beto O’Rourke at 6.6 (15.2%), senator Elizabeth Warren at 8.6 (11.6%) and former vice-president Joe Biden at 10 (10%). Longer shots include independent senator Bernie Sanders at 13 (7.6%) and Cory Booker at 13.5 (7.5%).
You can’t really write anyone off in the age of Trump, but we don’t think that O’Rourke really has much chance. While he ran Ted Cruz much closer than you’d expect, he still lost. Despite his undoubted charisma, he’s never been anything more than a junior congressman (a role he had to give up to run against Cruz). While he has a bright future ahead of him, it’s very hard to see how he could be nominated for president. So we’d tip laying him at 7.6, which translates to a bet against him at 1.15.
