I don’t think a Mondale endorsement will affect the outcome, but it’s an indication of the level of organization in the Hilllary campaign. They probably had his endorsement wrapped up long ago, paid for by some political promise benefiting Mondale, but they saved it for a moment of need. They’re probably saving even more important endorsements for when the Peter Paul stuff hits the fan.
Really, does anyone base their vote on someone out of the past, who a lot of people don’t even know? This guy was VP back in the 70’s, to a president who may have been the worst president in our memory, who cares what he thinks.
