I have to be honest with you, I think Christine O'Donnell's bid for the United States Senate will be difficult. She's a conservative in Delaware.But she has my full support.The thought of Mike Castle in the United States Senate makes me sick to my stomach.There is one practical reason to support Mike Castle. People tell me he will vote for the Republicans in the Senate leadership contest, potentially putting the GOP in the majority.But therein lies the problem with Castle. The man is to the left of Lincoln Chafee who himself was to the left of Arlen Specter. There are no guarantees when you combine a six year term with his age.People say Christine O'Donnell cannot beat the Democrat. These same people said Marco Rubio could not beat Charlie Crist in the Florida Republican Primary. These same people said Bob Bennett would never be defeated, let alone Mike Lee elected.Maybe they are right.But I tell you the truth whether you like it or not. If "these people" are right, I would still rather a Democrat I can oppose than a Republican who will oppose us.Mike Castle is a disgusting bottom feeder of a Republican politician and does not deserve anybody's vote. Better a Democrat than Mike Castle.But this is one of those unique election years where anything can happen. "Anything", in this case, is Christine O'Donnell getting elected. It could happen. I want to help make it happen. But at the end of the day, as long as Mike Castle loses I'm good.Don't give me the "he'll vote for Mitch McConnell" nonsense. What good is getting back the leadership with Castle's vote if he then spends the next six years selling us out not on one or two issues, but every single issue from abortion to cap and trade to Obamacare (yeah, he voted against it in the House, but wants to keep most if it now), etc.If O'Donnell can't win the general, better still the Democrat than Mike Castle.
