By letting Obama have his TPA it virtually guarantees passage with a 51 vote.
I get so sick of the “Don’t worry Mable, we’ll cut em off at the pass next vote!” mantra. We are such suckers.
I just got this off Wikipedia. The requirement seems to be that both houses pass the bill with a simple majority, but Hatch’s amendment can slow it down with 60 votes (a hurdle with Republicans in charge).
Procedure[edit]
If the President transmits a fast track trade agreement to Congress, then the majority leaders of the House and Senate or their designees must introduce the implementing bill submitted by the President on the first day on which their House is in session. (19 U.S.C. § 2191(c)(1).) Senators and Representatives may not amend the President’s bill, either in committee or in the Senate or House. (19 U.S.C. § 2191(d).) The committees to which the bill has been referred have 45 days after its introduction to report the bill, or be automatically discharged, and each House must vote within 15 days after the bill is reported or discharged. (19 U.S.C. § 2191(e)(1).)
In the likely case that the bill is a revenue bill (as tariffs are revenues), the bill must originate in the House (see U.S. Const., art I, sec. 7), and after the Senate received the House-passed bill, the Finance Committee would have another 15 days to report the bill or be discharged, and then the Senate would have another 15 days to pass the bill. (19 U.S.C. § 2191(e)(2).) On the House and Senate floors, each Body can debate the bill for no more than 20 hours, and thus Senators cannot filibuster the bill and it will pass with a simple majority vote. (19 U.S.C. § 2191(f)
