Grover Cleveland wasn't the first ex-president to try and run for president, but he is the only one to ever succeed. With that in mind, I'm wondering what presidents who could've tried but didn't in our timeline had the best shot of pulling it off. For the sake of the argument, their OTL presidency is unchanged. However, it goes under these stipulations
- Did not make a serious attempt IOTL(so T.R is out)
- Are eligible under the 22nd amendment(so Eisenhower, Nixon, Reagan, Clinton, Bush Jr and Obama are out)
- Are alive to do so(so Mckinley, Harding, FDR and Kennedy are out)
- Didn't die during what would've been their term had they been elected four years after their leaving office(so Wilson, Coolidge and LBJ are out)
