Using the definition provided by Wikipedia:
Neoliberalism or neo-liberalism[1] is the 20th-century resurgence of 19th-century ideas associated with laissez-faire economic liberalism and free market capitalism.[2]:7[3] While it is most often associated with such ideas, the defining features of neoliberalism in both thought and practice have been the subject of substantial scholarly discourse.[4] These ideas include economic liberalization policies such as privatization, austerity, deregulation, free trade[5] and reductions in government spending in order to increase the role of the private sector in the economy and society.[13] These market-based ideas and the policies they inspired constitute a paradigm shift away from the post-war Keynesian consensus which lasted from 1945 to 1980.[14][15]
I would go:
1)Reagan
2)Bush 2
3)Trump (tax cuts and deregulation outweigh protectionist trade policies in my book)
4)Bush 1
5)Carter (presided over the start of a period of deregulation that continued into the 2000s)
6)Clinton (governed liked a neoliberal-lite after 1994, but his push for universal healthcare as the key legislative initiative of his first term puts him below Carter for me)
7)Obama (the only one who wasn't really a neoliberal, though some of his officials were)
