I think you are onto something there. When was the last it took this many votes?

The speaker election last surpassed nine rounds in 1860, when Rep. William Pennington (R-N.J.) was elected after 44 rounds of voting during the 36th session of Congress. McCarthy previously made history on Tuesday when he became the first lead candidate since 1923 to fail to win on the first ballot. The record for most drawn-out House speaker election was set in 1856, at 133 rounds of voting.
