ITT: What major politicians have you met?

[TDAS04]

Only counting those I've interacted with:

Dennis Daugaard
Stephanie Herseth Sandlin
Dusty Johnson
Tim Johnson

I've also seen John Thune, George McGovern, Tom Daschle, Bill Janklow, and Jim Abourezk in person.  Bill and Hillary Clinton too, at a campaign rally.

Can't think of any others who were at least a US representative.
