Sen. Michael Bennet, D-Colo., the former Denver schools chief and one of the Obama administration’s go-to guys in Congress on education policy, beat back a primary challenge last night from Andrew Romanoff, the former speaker of the Colorado General Assembly.

Bennet is considered an education-redesign-oriented Democrat in a similar mold to these guys. He also introduced a bill on helping to train principals to do school turnaround and is said to be working on key teacher legislation.

He will face off against Ken Buck, who was backed by some local tea-party activists. On his campaign website, Buck called the American Recovery and Reinvestment Act, aka the stimulus, “porkulus.” Buck beat Jane Norton, the state’s former lieutenant governor, who was originally expected to sail to victory.

This should be a fun race to watch in November.
