Both parties do this every election cycle, they promise the world and hardly deliver on anything meaningful in the end once the congress and senate get there hands on the bills they send up. If you really think Bernie and now Hillary are going to be able to raise taxes high enough for people to get free college degrees, then you really are just another in a long list of sheep that came before you. Even Obamacare that was bandied about as being something wonderful is starting to show its ugly head. The various thing that were told early on about how it was going to drive up cost are coming true and many that had insurance last year won't be able to afford it this year.
None these people running for president will do much of anything, because it just won't happen, because they simply can't deliver on their promises. Executive orders can only go so far and they are not permanent. If any of these people plan on really doing anything they are going to have to work with congress and the senate and it won't matter which party is in control. Both these parties literally suck ass and the last couple president's and their congress's have done more to tank this country, then all the other ones combined.
