DENVER — Republicans aren’t close to having a challenger to take on Democratic Colorado Sen. Michael Bennet next year but that isn’t stopping them from continuing to try to soften him up with a barrage of early attacks.

After launching robocalls against Bennet earlier this month, the National Republican Senatorial Committee is out with a new video drilling the Democrat for his party’s recent filibuster of what had been a bipartisan bill to combat human trafficking.

But the video ignores important context around that legislation, which Democrats blocked only after learning that Republicans included language in the bill to restrict federal abortion funding.

“Senator Bennet is so entrenched in the partisan politics of Washington that he would rather cave to party leaders than stand up for victims of human trafficking,” said NRSC spokesman Matt Connelly. “Coloradans want their elected representatives to be problem solvers, not part of the problem, but unfortunately that’s exactly what Senator Bennet has become.”

That quote is at odds with Republican Congressman Ken Buck’s characterization of Bennet, who he lauded for being a “bipartisan problem solver” during a FOX31 Denver interview last June.

Bennet, in fact, is a co-sponsor of the clean bill that combats human trafficking without impacting abortion funding.

“The lengths that Republican Senators are willing to go to attack women’s health, even at the expense of victims of human trafficking is simply unconscionable,” said Justin Barasky, Communications Director for the Democratic Senatorial Campaign Committee.

“How much longer will the Republican Senate tell victims of human trafficking that their plight is less important than the GOP’s continued goal of taking away the rights of women to make their own decisions?”

Bennet is one of the few vulnerable Democrats facing reelection in 2016.

Republicans appear to be a long way from settling on a challenger, with many of the party’s best options — Treasurer Walker Stapleton, Attorney General Cynthia Coffman and Arapahoe County District Attorney George Brauchler — all preferring to run for governor in 2018 over challenging Bennet next year.
