Colorado's two freshman senators, Mark Udall and Michael Bennet, are part of a self-described centrist group of 15 Democrats meeting regularly "
seeking to restrain the influence of party liberals in the White House and on Capitol Hill," according to an account in Roll Call (subscription required).
The group has a "shared commitment to pursue moderate, mainstream and fiscally sustainable policies across a range of issues, such as health care reform, the housing crisis, educational reform, and energy policy," according to a statement issued Wednesday by the group.
