>> fairly quick, more than most people, they understand that we have 51 elections in november, not just one that the polls always talk about. that's because the voters in each state decide which states will get their elector ral vo-- the money that they -- for that reason, you can expect all the delegates, including those in california to return home ready to go for the november 6 march and let me tell you, they will be primed. >> okay, larry, thank you very much for their insight. >> was it murder?
