Remember that the "me too" wing of the GOP had become dominant in the 1940s, with Presidential nominees Thomas Dewey and Wendell Willkie part of that faction, the predecessor to today's RINOs. Robert Taft led the conservative wing of the GOP; he would have reversed the New Deal and thoroughly purged the Communists and their sympathizers from the Federal government. Unlike Reagan or Trump, Taft was not a charismatic personality, while Eisenhower was well liked as the man who led the Allies to victory. At the time, the California GOP was conservative, but Earl Warren and Richard Nixon cut a deal with Eisenhower to have the Golden State delegates to the Republican Convention support the former general. The price was that Warren became Chief Justice and Nixon became Vice President.
Too bad Patton couldn’t have been elected in 1944 and then succeeded by Taft/MacArthur in 1952. Taft, of course, still would’ve died in the Summer of 1953 due to his poor health, which would’ve elevated VP MacArthur to the top job after just 6 months. It would’ve been curious to see what this trio could’ve done over a 16 year period to bring the country back to the small-government and low-tax 1920s (albeit with a stronger and larger military). The prosperity and growth would’ve been without equal. We’d probably be 100 years ahead of where we are today across the board.
