Multiple individuals have tried and eventually won the US presidency. Here are some examples:

1. Richard Nixon: Nixon ran for president in 1960 but lost to John F. Kennedy. He ran again in 1968 and won.

2. Ronald Reagan: Reagan ran for president in 1976 but lost to incumbent President Gerald Ford. He ran again in 1980 and won.

3. George H.W. Bush: Bush ran for president in 1980 but lost to Reagan in the primary. He was chosen as Reagan's running mate and served as Vice President for two terms. He then ran for president in 1988 and won.

4. Grover Cleveland: Cleveland ran for president in 1884 and won. He lost his re-election bid in 1888 but won again in 1892.

5. Thomas Jefferson: Jefferson ran for president in 1796 but lost to John Adams. He ran again in 1800 and won.

It is worth noting that not all candidates who tried multiple times were successful. For example, Hillary Clinton ran for president in 2008 and lost the Democratic primary to Barack Obama. She ran again in 2016 but lost to Donald Trump.

In conclusion, multiple individuals have tried and eventually won the US presidency, including Richard Nixon, Ronald Reagan, George H.W. Bush, Grover Cleveland, and Thomas Jefferson.
