Oh, hell, they'll probably fool me again. But the Republicans have seemingly stumbled upon the magic formula of fiscal sanity, and limited government as the touchstones of their 2010 campaign. I have always said that I believe in the principles of the Republican Party, even if they don't.
For those social conservatives, I would say to not fear the change. Limited government is less likely to force government mandated abortions or gay marriage, because that is not the proper role of government. A Win-Win for both fiscal and social conservatives.
Republicans always said that government doesn't work, and when elected proved it. The Democrats of today seem to believe that the government can solve all problems, and they promptly show that they are horribly wrong. Maybe we should stick with the ones who were right.
On the other hand, if the Republicans decide to revert back to the previous eight years, there will be a quick turnaround again. You get one more chance Republicans. Don't blow it.
