Spanish American War Tax Dead → Should I thank my representative?

I recall writing in to Specter and Santorum and eventually got the nice letterheads back thanking me for feedback. Rick Santorum went further with another letter (generic?) explaining his position to repeal this useless, outdated tax.
I should write him back, thanking him for his efforts.

Rick has been getting alot of flack lately here in Pa, but he has showed up at more rallys and gatherings locally than any other politician this side of the Mississippi. He is a man for the people, that is currently getting a bad rap........ Go Rick
