I sincerely hope this is a rhetorical question. Do you really not know the difference? Do you really think that judges following, being bound and restricted by the Constitution is no different than judges who bend and twist the Constitution to fit their particular ideology?
The difference is the rule of law vs. the rule of five.
It's the difference between By the people, for the people and of the people and By lawyers, for lawyers and of lawyers.
It's "obey your sacred oath of office" or "obey your particular ideological leanings"
There is no difference! Progressives and Constructionists have become the same thing! Which wants to see a reduction in the size of the federal government? You'd think it be the constructionists, but why aren't the alleged "constructionists" in office now repealing federal programs en masse? Because they are really progressivist liberals? Or is it because there is really no difference anymore?
