Draft Colin Powell. Sure, he's a bit old, but convince him to give his country one four-year term and get things calmed down.
To conform a little to the o.p., maybe Johnson.
I did not see a single name worth my putting a stamp on a vote by mail envelope. Colin Powell has something in his background that would not withstand scrutiny. Years ago when it was originally suggested that he run for office, he said no because he did not want to put his wife through digging into his past.
