Jeb Bush gets back in the race by naming himself Hillary Clinton's strongest opponent

A feisty Jeb Bush sought to regain his footing in the Republican presidential race, casting himself as the strongest election opponent for Democratic frontrunner Hillary Clinton.

The former Florida governor took advantage of a policy-focused debate to detail positions on the economy and immigration.

The televised debate is the last for the Republicans until mid-December, and could help shape the course of the campaign into the winter.
