Er, no. The Senate Commerce Committee shut down the Blackburn Amendment strictly along party lines for one reason and one reason only: the Democrat's alliance with unions (ALPA and AFL-CIO in this case.) There is no raging anti-67 sentiment in the general public (who don't know and, generally, don't care) or the Senate. With Manchin and Kelly being co-sponsors of the original stand-alone legislation, if you polled the Senate as a whole it would probably break by one or two in favor of 67. It was hardly a "Congressional win", as you put it - maybe a Senate Committee "win". But, at the moment, it's a Congressional tie with floor amendments (high bar) and Conference Committee still very much in play.
