I think so, but I might be biased. John McGinnis argues that they believe that they must in order to maintain a fragile coalition of votes and interests.:
From its inception, progressivism has posed a threat to constitutional government. It has sought to replace limited and decentralized governance with dynamic, centralized authority in order to force some arrangement of equality on the nation. Because the world has a way of upsetting abstract designs, progressivism depends on empowering administrators to impose its frameworks while disempowering citizens from resisting these coercions. The Obama administration’s push for unilateral presidential authority to disregard the law is thus the logical extension of the progressive program. Opposition to this program requires nothing less than a rededication to our Founding ideals: our nation must be governed by the rule of law, not the rule of an elected monarch or of a legally privileged aristocracy.
