Plus Ike’s first big mistake for the SC, Earl Warren.
Earl Warren was a RINO before the name was applied. Governor of California (1943-53) and big power in the National GOP, being Eisenhower's prime GOP opponent. Nixon, then US Senator from California, worked a Convention deal for the California Delegation to switch their votes from Warren to Eisenhower after the 1st vote. The reward to Warren was the 1st Supreme Court (SC) open position nomination which was (unfortunately) Chief Justice Fred Vinson's death (8 September 1953).
Warren was CA Attorney General but never a judge and thus gave little warning on how much of a loose cannon he was. The US Senate (48 States, 96 Senators) was R48, D47 and Wayne Morse of Oregon (I) but having switched from GOP at Eisenhower's election (in 1955 he went 'D') so the Senate was split with LBJ a powerful 'D' Minority Leader as GOP Majority Leader Taft had just died and William Knowland (CALIFORNIA) was a fill-in. So you could say that Warren had everything in his favor. Warren was confirmed (March 1954) after his recess appointment (October 1953) by acclimation.
