Colorado to be part of a national primary?

Via CBS:

After a handful of key contests spread throughout late January, a glut of states awaits on Feb. 5 - a day that threatens to become the equivalent of a national primary. The list of states that are holding contests on that day is significant: Alabama, Arizona, Arkansas, Delaware, Missouri, New Mexico, Oklahoma and Utah. But other states - California, Colorado, Illinois, Florida, Michigan, Montana, New Jersey, Texas and possibly more - are moving to join that club.
