It won't get 60 Senate votes. I am going to walk a line with a general explanation. It is neither endorsing or condemning a position.
In general, Democratic Senators are going to be sensitive to the rights of the athletes (employees, if you will.) They will generally oppose rules that give the Athletic Departments control over things that were unleashed by the Supreme Court Ruling. They would generally support Collective Bargaining with whatever Central Entity/Employer that can be agreed upon.
In general, Republican Senators would be more sensitive to the rights of the Schools/Athletic Departments (Management, if you will). They will be in favor of not having the athetes ever considered employees and will be leaning to management decisions and individual Conferences or even Schools autonomy. They are fundamentally wary, if not outright opposed, to Collective Bargaining.
And, like it or not, the fact that a high percentage relative to the general population of FB and MBB players (the 2 revenue generating sports) are Black, creates, at best, tension and in some cases outright hostility most often on party lines.
Add in women's sports and Title IX issues, and it becomes apparent this is not a simple, easy fix. It started when the Supreme Court ruling upended what we had known. It magnified with the blatant absolute greed of the $EC and B1G grabbing money, money, money.
The answer is to fashion a compromise, which is what Cruz-Cantwell is. The problem is selfish intersts are working against compromise. We may actually see the demise of College Athletics because compromise has become a dirty word - in a nation literally founded on compromise.
