As a one year Governor, I believe Brown would need a Senator similar to Carter, as Vice President, list of possible running mates:
- Birch Bayh, Senator from Indiana since 1963. He is the only non–Founding Father to have authored two constitutional amendments. Bayh also led unsuccessful efforts to ratify the Equal Rights Amendment and eliminate the Electoral College.
- Walter Mondale, U.S. senator from Minnesota since 1964 and OTL 1976 running mate.
- Abraham Ribicoff, US Senator from Connecticut since 1963 as well as Representatives, 80th Governor of Connecticut and Secretary of Health, Education, and Welfare in President John F. Kennedy’s cabinet. He would become the first Jewish candidate on a major American political party presidential ticket.
- Edmund Muskie, Senator from Maine since 1959, he was the running mate for Herbert H. Humphrey in 1968. IOTL he was Jimmy Carter’s Secretary of State.
- Adlai Stevenson III, Senator from Illinois since 1970, his great-grandfather Adlai E. Stevenson I was Vice President of the United States (1893–1897) during Grover Cleveland's second term. His grandfather Lewis Stevenson was Illinois secretary of state (1914–1917). His father, Adlai Stevenson II, was governor of Illinois, Ambassador to the United Nations, and two-time Democratic presidential nominee.
- Russell B. Long, Senator from Louisiana since 1948, over his 28 years, his views went from conservative to moderate.
- Ted Kennedy, Senator from Massachusetts since 1962.
- Thomas McIntyre, Senator from New Hampshire since 1962.
- George McGovern, Senator from South Dakota, since 1963, he was also presidential nominee in the 1972 presidential election.
- Jennings Randolph, Senator from West Virginia, since 1958.
- William Proxmire, Senator from Wisconsin, since 1957.
- Lloyd Bentsen, Senator from Texas since 1971.
- Gaylord Nelson, Senator from Wisconsin1963.
- Joe Biden, Senator from Delaware since 1973.
- Mike Mansfield, Senator from Montana since 1953 and was retiring from the Senate in 1976.
I’ve left off all southern democrats senators as doubt they will help the ticket.
All these senators have the option to serve in Brown’s cabinet.
