What is making the Republicans so nervous?

There's an excellent article in today's Inquirer that reports a shift away from Republican registrations in the suburbs. This is good news. Although it wasn't cited as a reason in the article, I think many of these conversions are due to the Bush administration's failures. Progressives are certainly against their policies, but are now being joined by true conservatives as well. Weldon doesn't want Bush to campaign for him, and I doubt Santorum will either. Look for more gains between 2006 and 2008, especially if Sestak and Casey prevail. The Republican strangle hold is loosening in Delaware County to the point that we may actually see Democrats entering in previously uncontested local elections. That's a win for democracy.
