History doesn’t seem to be your strong suit, Chuck.

ObamaCare was passed based on a 60 vote majority prior to Brown winning the seat formerly help by Ted Kennedy. However, it had to go to the House and be passed there. Pelosi refused to allow any amendments, so it went back the Senate intact and was passed under reconciliation. If it had not been passed in final form under reconciliation, it would not have gotten past the 60 vote requirement for consideration. (Thanks to Rick C)
