Absolutely! Open primaries need to be eliminated...NH raised McCain's candidacy from the dead...thanks, 'Free State'. (Vermont pulls this stunt, as well...they cross over and select the worst possible Republican candidate in the primaries to give the Democrat the best chance of winning. That is why we are stuck with Leahy, for example. Democrats voting in the Republican primary nominated a semi-literate dairy farmer back in the late 90's, and Leahy beat him like a drum.)
This is a first and mandatory step. Next, raise money. We will never come to the level of Soros but we may be able to spend more wisely.
