Hamilton was a big government guy. Lincoln too, and Teddy Roosevelt. Hoover started many programs picked up by FDR. Wilkie was a democrat until 4 months before his nomination. Eisenhower was a democrat. Nixon kept all of LBJ’s big society programs. Then of course there was Voodoo Economics HW, and now Compassionate Conservative GW Bush.
So, Reagan and Calvin Coolidge where it.
Oddly, Reagan said that he voted for FDR four times and HST once, and Coolidge is the only one to have defeated FDR in an election (as Harding’s VP candidate).
Cleveland was said to have been more conservative than Arthur or Harrison.
