Her proposal is just plain stupid. If she were actually serious, it would be the maximum costs of a 2 year community college degree plus 2 years at a state college/university for bachelor's degree. Let's see, that's about $10k max. If you're spending more than that for a degree, you really ought to take some responsibility for it.
Won't stop her from pandering.
Actually, its a very smart proposal. She realizes the vast stupidity of voters these days and knows how to capitalize on it. Who cares about actually living up to her promises. None of the previous Presidents have lived up to theirs and people don't hold them accountable, so why not promise it to the mob if it gets you elected? Since when do proposals have to have any realism in their design?
