He calls it "Romentum" and Andrew Romanoff thinks he sees plenty of reason for optimism after "Super Saturday"."We figure we got outspent 10 to 1," Romanoff said. "So, yes, we're pleasantly surprised to do as well as we did today and I think it's a sign of things to come. I feel very good about where we are."Painting incumbent Senator Michael Bennet as a Washington insider, Romanoff said he thinks Colorado voters are unhappy with the pace of change coming from detached, wealthy lawmakers in the nation's capitol."That's why I think the folks in Washington act sometime as if they had all the time in the world. But they don't, and we don't. I think today sent a wake up call, a shockwave to a town that needs one," Romanoff said.With results still coming in, his campaign declared victory in major counties holding Saturday assemblies, such as Denver, Jefferson, Arapahoe, Douglas, El Paso and Pueblo.What's at stake for the winner is the top line on the Democratic primary election ballot Aug. 10.Romanoff is one of three people trying to unseat Bennet, chosen by Gov. Bill Ritter to replace Ken Salazar, who now serves as Secretary of the Interior. The other two candidates are vying for the Republican nomination; former Lt. Gov. Jane Norton and Weld County District Attorney Ken Buck.While Republicans didn't cast votes for their Senate candidates, it was a chance to gauge enthusiasm.Some 1,800 Republicans attended a caucus event in Colorado Springs amid hopes that change will bring them more seats in Congress.The polls give them reason for hope.The latest Rasmussen Reports poll released Thursday showed Jane Norton with a 5 percent lead over Bennet and an 11 percent advantage over Romanoff."At each of the assemblies I attended today, people were saying the same thing: the federal government is out of control," Norton said. "Overspending, overtaxing, and over-regulating is striking at the core of who we are as a nation. I'm very grateful for the tremendous support I received today and throughout this campaign, and I look forward to continuing the fight to unseat Governor Ritter's appointed Senator."Colorado State GOP chairman Dick Wadhams said enthusiasm is growing amongst Republican voters for the Senate race."The large, enthusiastic crowds at Republican county assemblies across the state today are indicative of the optimism Republicans have for the November election," he said.Both parties have their state political convention set for May 22.
