has a Democratic candidate ever swept the primaries?

[pruner]

if not, what's the closest anyone's ever come?

on a related topic, what's the least # of primaries a candidate has won and gotten the nomination.

[TSIAS]

1. I think Gore came close

He got around 90 % of the delegates in 2000. I don't recall Bradley winning any states.

2. Yes Gore in 2000

won all 51 contests in the US proper and won the other 3 in places like Guam etc.

3. Certainly Clinton did it in '96

And, yes, I don't remember that Bradley won any of the primaries.

5. I meant a contested primary

4. LBJ

1964, if it wasn't a sweep, it was damn close to it.
