Wasn't Sanders saying free college for all? He seems to have changed what he was saying before.
He's always specified that it's not simply free college in general for all, but specifically free tuition for public schools. The questions posed are always phrased as free college for all, and he has to correct it every time.
The framing was different before. As I recall, he was promising free college for all and saying that it would be a cost savings, similar to single payer health care.
If you can find an example of that my apologies, but I don't believe that is true.
He introduced a bill called the Free College for All Act. In addition, his framing in earlier debates was not the same as it was tonight.
The very first line in the summary description of that bill is: "Eliminate Undergraduate Tuition at 4-year Public Colleges and Universities". Again, just find one clip or quote suggesting otherwise.
The title of the bill speaks for itself. Watch any previous debate or forum it is clear that he has changed his framing. He repeats himself all the time, so it's not hard to find.
No he hasn't, it has always been crystal clear that it would be only in public colleges and universities.
