I posted on Rose's blog the definition of "progressives" as:
Progressives are Political people who are moving forward; proceeding onward; advancing; evincing progress; increasing; as, progressive motion or course; opposed to retrograde. Improving. Promoting or favoring progress toward better conditions or new policies, ideas, or methods. Favoring or advocating progress, change, improvement, or reform, as opposed to wishing to maintain things as they are.
That started debate that delved more into semantics.
I consider myself a "progressive" and I am more of a "Doer" or "Trier" than a "Talker." I have a record backing that.
Advocates for "improvement" is best summation. But that is just one opinion.
The "progressive" label can fit both Liberal Democrats and change minded Republicans. Just look at their agenda and record.
