First let me say, Mike Castle is not going to run for the US Senate. Period. Book it. Take it to the bank. He is going to see no profit in spending 12 to 18 months of his life actually working the campaign trail for the first time in 20 years in order to finish his career with a loss to whoever the Dems put up.
It isn’t happening.
However, if he did decide to do it, he would get some National Republican Senatorial Committee (NRSC) money because it looks like very few other serious people in the country will be running for the US Senate in 2010 as a Republicans.
