Bennet nearly doubles Norton's first quarter total

Sen. Michael Bennet (D-Colo.) announced Tuesday he raised more than $1.4 million last quarter. His campaign said part of the haul came from 12,000 new donors. It declined to reveal its cash on hand.

Bennet's primary challenger, former state House Speaker Andrew Romanoff, has yet to release his first quarter numbers.

Former Lt. Gov. Jane Norton, the leading candidate in the Republican primary, announced last week that she raised $816,000 in the first quarter – a 48 percent increase over the previous term, her campaign said.
