Gardner, Udall spar in feisty second debate
DENVER -- Two partisans, locked in a tight race to win over moderate voters in this purple state, sparred for nearly an hour Monday morning over their respective records in Washington. Democratic Sen. Mark Udall defended his support for Obamacare and underscored his support for a tax on carbon pollution, while criticizing Republican Congressman Cory Gardner's voting record as being "out of the mainstream."
