“Anything can be filibustered.”
If that were true then how was Obamacare passed with 56 Dem votes.There are exceptions If the bill is couched in terms of a financial reconciliation bill then a simple majority was needed. The Dems practiced chicanery in passing the bill as if it were a financial reconciliation bill. If you live by the sword you die by the sword should the Republicans decide to use the same ploy to repeal it.
ObamaCare passed the Senate with 58 Dem votes and 2 independent votes.
