Joke only started promising it prior to the election so not sure how many made the decision to take out a college loan based on him. But yes, he knew he couldn't do it and Nan told him he couldn't. It was a lie to get people to vote for him and to make the Rs look bad when it rightfully got shot down. But they don't care about what's right or wrong, just that they didn't get money back from the taxpayers, when it was the colleges who set the tuition costs and got the money.
