WJC is speaking at HRC fundraisers all over the country. These events are of some interest locally for a few days before he arrives but are generally low-profile, and raise loads of cash. Local Dems with money pay thousands to hear him speak for half an hour, and thousands more to shake his hand or get a picture taken with him.
Among the Democrat Faithful, Bill Clinton remains a superstar - the greatest President in memory - and he can bring in the bucks like no other political "Star."
As for national coverage, who cares what he has to say about anything? Would anyone be more likely to vote for HRC because her disgraced husband endorses her? Are you kidding?
