According to PredictWise, which aggregates the results of betting markets, the candididates' chances of winning the nomination are now 54% Rubio, 26% Trump, 13% Cruz, 4% Bush. A day ago, before the Iowa cacuses, the chances were 51% Trump, 33% Rubio, 10% Cruz. So the biggest winner in Iowa was Rubio. I think Rubio is the most electable candidate, because Cruz (who I like) is too conservative for the country. If Rubio is elected president, I hope the congressional GOP can stop a bad immigration bill, as it did under George W. Bush.
