Nevertheless, on Aug. 8, 1935, the conference report — the final version of the bill that melds together changes made in the House and in the Senate — passed in the House 372-33, with 81 Republicans voting in support.

Thirty years later, a significant number of Republicans voted in favor of the Medicare bill. The House adopted the conference report on July 27, 1965, 307-116, with 70 Republicans supporting it. And on July 28, the Senate adopted the final version of the bill by a vote of 70-24, with 13 Republicans in favor of the bill. President Lyndon B. Johnson signed the Medicare bill into law on July 30, 1965.
