As for defunding...
Some judge will deem “defunding” as a bill of attainder, and presto, funding must continue...EXACTLY the approach undertaken with ACORN to ensure they’re still on the taxpayer teat.
That would be a stretch.
Anyhow we’re talking about withholding votes for future funding of ObamaScare.
With respect, a Bill of Attainder is singling out 1 human being or corporate organization for de-funding or for some other penalty.
E.g. ACORN gets no funding.
OR
Sylvester Stallone shall get no money from the National Endowment for the Humanities.
De-funding ObamaCare doesn’t single out anyone. It just says we’re not funding a broad range of coercive activity, that would otherwise target countless individuals and businesses.
