Republican Party Results, County by County

I have refrained from talking about Google's Politics and Elections page as it has been a lot of results based on searches in a particular area of the country.  But you might want to put it on your iGoogle or Google+ page and look at it from time to time.  This page, for example is quite good as you can run your cursor over the page and see results in ever district, county, etc.  You can also roll your mouse and go in for a closer view (or just the opposite).
