Not at all, a remotely descriptive name would be far easier to fabricate than a hideously contrived backronym. Naming something is nontrivial, as a developer I understand and appreciate that, but that's no excuse for creating misnomers with the express intent of manipulating other people.

I highly doubt it, I'm fairly certain bill names are only to mislead the public as there's a pretty clean dichotomy between the two parties in the U.S. and their votes are usually a pretty standard party split.
