I think you are mistaken. An incredibly small number of votes are needed to win a primary in this state. Castle's TV buys will mean nothing. They won't motivate the average Republican (the only ones who can vote) to actually get to the polls on September, 14. But believe me, pissed off Republicans will be there. Help her if you can. I am watching this unfold and I really believe she can kick his butt.
Is Delaware’s primary open or closed?
