Udall's campaign has argued that it has an advantage in the race's final days because it and its Democratic allies are scheduled to air more ads than Gardner and Republicans — a reflection of how Democrats were able to purchase air time earlier in the election, when it was cheaper. All voters were mailed ballots that can be sent in the mail or, starting Monday, dropped off at polling places around the state. The new voting laws were passed by the state's Democratic-controlled Legislature over Republican objections last year and are expected to help Udall, who has trailed in recent public polls.
