Actually, I wasn’t please with Cruz’s 16 hour(?) filibuster last year, either. If these guys are going to do this, they really need to have them last a serious amount of time.
Again though I would say that these sort of non filibusters do actually give a lawmaker sufficient time to educate people about complex issues. Otherwise all you hear is what Mitch McConnell, Orrin Hatch, etc have to say on the matter and they are mostly always lying.
Also it does my heart good to see a few guys stand up once in awhile. :-)
