(CNN) – Crossroads GPS is not waiting for the dust to settle on the debate over student loans in the U.S. Senate. The Karl Rove-backed super PAC has already launched a small online ad campaign against four Democratic senators it blames for not stopping the rate hike.
Display ads launched on Facebook Friday will target college students and young people in Alaska, Arkansas, Louisiana and North Carolina, calling out their respective senators Mark Begich, Mark Pryor, Mary Landrieu and Kay Hagan. All are Democrats.
According to a statement from Crossroads GPS, the ad campaign tells those who read it that their respective senators are "holding your future hostage."
Student loan rates doubled July 1 from 3.4% to 6.8% after Congress failed to reach a deal averting the increase. Efforts to retroactively lower the rates foundered Thursday after a report from the Congressional Budget Office estimated the current plan to lower rates would cost $22 billion over 10 years.
In the meantime, voices on both sides of the aisle have begun blaming each other for their inability to pass the legislation.
The Crossroads campaign will cost a modest $50,000, the group said, a drop in the bucket when compared to past efforts. In the 2012 federal elections, the group spent $176 million, according to OpenSecrets.org.
