Obama was such a disappointment. He came in preaching change and just rolled over the last part of his presidency. He was a solid president, but he changed little, after talking such a big game in 2008. Obamacare was even a Republican plan previously. The only guy who went to jail for the financial crisis was a whistle-blower. Good luck seeing anyone from the financial sector do that again.
IMO, If you want major change, don't vote for any candidate that got a degree from an Ivy League school. The connections they make there are exactly the people who will be hurt most by changes to help the majority of Americans. Lately, that is where almost all our presidents have attended. Previously they came from a much wider variety of schools. Since 1988, all our presidents received a degree from an Ivy league school: Trump (Penn), Obama (Columbia and Yale), Bush II (Yale and Harvard), Clinton (Yale), and Bush I (Yale). During that time we have been in several wars, income equality has risen steeply, the money floodgates were opened for the rich and corporations to heavily influence our elections, banking regulations were weakened and not enforced properly, taxes keep getting lowered on the rich and corporations, etc.
