Which American has won the most votes in history?

[Del Tachi]

Biden really shouldn't count, since people don't vote for Pres/VP separately

For non-presidential candidates, I'd guess....Dianne Feinstein?

Now doing this for Jerry Brown:

1970 (statewide):  1,632,886 (D primary)
1970 (statewide):  3,234,788
1974 (gubernatorial):  1,085,752 (D primary)
1974 (gubernatorial):  3,131,648
1976 (presidential):  2,449,374 (D pri5mary)
1978 (gubernatorial):  2,567,067 (D primary)
1978 (gubernatorial):  3,878,812
1980 (presidential):  575,296 (D primary)
1982 (senate):  1,392,660 (D primary)
1982 (senate):  3,494,968
1992 (president):  4,071,232 (D primary)
1998 (mayoral):  48,129
2002 (mayoral):  42,892
2006 (statewide):  1,552,922 (D primary)
2006 (statewide):  4,756,184
2010 (gubernatorial):  2,021,189 (D primary)
2010 (gubernatorial):  5,428,149
2014 (gubernatorial):  6,743,137*

Total: 48,107,355 

*includes runoff totals

So Feinstein actually beats Brown by ~6 million votes, which is not something I was expecting
