As a former Republican, I represent a group of Americans who all too often have no one to speak for them. This group doesn't necessarily have a name. We've been called 'moderates,' but that term can be misleading.

I talked to a lot of employers who just are, are fearful of what's coming next out of Washington. It's all the spending, it's all the debt. It's their national energy tax, they want to call it cap and trade - more mandates, higher costs, more taxes. Their healthcare bill - more mandates, higher costs, higher taxes.
