The Biden/Harris administration will vigorously pursue uniparty policies with the quiet acquiescence of uniparty Republicans. From Jeff Deist at mises.org:
Paraphrasing the late Murray Rothbard, the “two party” system in America during the twentieth century worked something like this: Democrats engineered the Great Leaps Forward, and Republicans consolidated the gains. Wilson, Roosevelt, and Johnson were the transformative presidents; Eisenhower, Nixon, and Reagan offered only rhetoric and weak tea compromises. In politics, being for something always beats being against something, and Republicans were never much against expanding federal power provided they had a place at the trough.
George W. Bush challenged this dynamic in the early twenty-first century. Despite his own intellectual incuriosity, he used the terrorist events of 9-11 to advance a particularly noxious “conservative” foreign policy and justify a growing domestic surveillance state. The results were plenty transformative, from the Ashcroft/Yoo doctrine of unitary executive power to initiating two disastrous Middle East wars. Renditions, CIA black sites, waterboarding, and Guantanamo Bay all became part of the national lexicon. And everyone got paid, from Big Pharma in the form of a Medicare Part D drug benefit to teachers’ union bureaucrats supporting the Bush–Ted Kennedy alliance known as No Child Left Behind. Throw in the Orwellian Department of Homeland Security and its Transportation Security Administration, and Bush’s most visible legacy may be forever ruining air travel in America.
