Does Senator Grassley understand "ex post facto"?

From a release dated 17 December 2004:

• Sen. Chuck Grassley, chairman of the Committee on Finance, and Sen. Max Baucus, ranking member, today said they plan to put forth legislation early next year that would increase and create additional fines and penalties on promoters, taxpayers and appraisers who participate, aid or assist in the donation of facade easements found to be significantly overvalued. The senators plan to make the additional fines and penalties effective today.

And these "Republicans" are supported by the majority of the country?
