of his policy wasn't a great idea. They may have voted for Obama but the voters in question also did what they always do and continued voting straight republican in every other election. During his 8 years in office Obama fulfilled his duties as president with intelligence, with a style and grace that republican presidents never seem to bring to the table.
Obama brought us, and the world, back from the brink of economic collapse. He made it look easy, too easy. So, that particular segment came to the conclusion that if a N***** could do it, anybody could. Then they decided to test their little theory by placing the most ridiculous fleaball momo they could find into office.
If these voters didn't find any change it's because they didn't want to. During his time Obama had a number of different jobs acts and programs put in place to close the "skills gap". I guess the "Obama-trump voters" decided to forget how THEY rejected it all out of hand. The tax breaks we were given for returning to college and programs initiated for retraining to other careers. Things were put in place to help them succeed and they turned it all down.
They didn't, and still don't want any sort of real change. They want to exist in a world where they have no competition, and requires one to put forth zero effort to maintain marketable job skills. Ever the consummate con-men trump and the GOP know their marks quite well.
