If Mark Udall had a last name that wasn't associated with a strong tradition of progressive politics in Arizona, of all places, I would still think he has the makings of an excellent Senator based on his record in Congress.
While the term "progressive" is usually associated with people who want to be thought of as further left than "liberal," we will add this reference to the "liberal" count.
The Mark Udall is not a moderate scoreboard:
reliably left wing 5
We started this scoreboard when we noticed that liberal blogs and the msm were routinely calling Mark Udall a "liberal," "reliably left wing," and even "extremist." We do not count comments from conservative blogs and we didn't count a comment on a liberal show by a conservative politician. Those who would like to check our methodology can follow the bread crumbs backwards
Added: Another liberal blog has just quoted SquareState verbatim. We are therefore incrementing the liberal count from 23 to 24 without creating another post.
