I finally tracked down the blogger and here's the story. Sen. Simpson was co-chair, along with Democratic Sen. Erskine Bowles, of the Simpson-Bowles Commission, which was yet another attempt to address ongoing budget deficits and set the Federal budget on firmer footing. Taking an "all options on the table" position they were seriously considering adopting a Value Added Tax (VAT) as is employed by many countries in Europe. Not liking that idea one bit he made a post mildly criticizing Simpson for agreeing to consider this. And amazingly enough a few days later he actually got a call from the Senator taking issue with his post.
Whatever that conversation sounded like it must have been cordial because he said he was bummed out to hear about Simpson's death.
We were both amazed that the Senator tracked him down based on a post in a Web 1.0 blog that was read by at most a few hundred people.
The VAT idea got steamrolled by the Tea Party Movement in a way that tiny blog could never hope to do.
