My argument isn't that the U.S. was better before Obama. Of course, if you compare any president to Bush you'll see positives. I'm not saying Obama hasn't done good things. I'm saying Obama is a fucking snake who has sold the United States to the highest bidders.
On the contrary, the practice of selling to the highest (or lowest in the case of labor) bidder has been around, literally, hundreds of years. That isn't Obama, that is capitalism. If you have an issue with that then I suggest you join a socialist movement, rather than railing at someone who worked for eight years, against an actively hostile and non cooperative, GOP controlled, senate, to push through legislation. Of course, nobody would expect the GOP to agree with everything that Obama was doing, discussion (and crucially, resolution) is the essence of politics, however the GOP filibustered things that even they, ideologically, agreed with - just to slow the process down, just to make it harder for the man to affect changes to the established order.
Obama is the first president to be denied a hearing on his budget.
Obama is the first president to be denied a hearing on his supreme court nominee.
Obama is the first president to show his birth certificate.
Obama is the first president to face over 500 filibusters by the opposition.
Also, I'm not just comparing Obama to Bush. Obama is bested only by Bill Clinton, and Regan. Carter is close behind, which is a wonder given the mess he inherited after Nixon. They are trailed by bush snr and jnr who perform significantly worse. In all of these presidents, none faced the problems from within the legislature that Obama did, yet he still boasts the third strongest economic data in the last 60 years and after the worst financial disaster since the great depression. All this boils down to one simple fact; the GOP prevented Obama from making america even stronger and more equal. They prevented progress. By preventing progress, they created a climate in which a man like trump could take advantage of the frustrations they had created in the nation. Trump is the pawn of establishment GOP. He is their creation. You can see it in their endorsements, financial and verbal, you can see it in their actions over the past eight years. If you vote trump, you won't be getting a "great liberator", you will be getting the GOP establishment's Frankenstein monster; Egotistical, authoritarian and backward.
