The Dems have a way lower approval rating than Trump right now, but I'd put my money on the fact that you probably didn't know that. People are tired of same old politicians peddling their same old bull. That's why nobody approves. Interestingly enough, for as polarizing as Trump is, he's got one of the highest approval ratings in DC right now, while having the lowest in modern presidential history. Now what exactly does that say?
To me, it shows a huge opportunity for successful private sector leaders such as Iger and Oprah to consider running for the presidency. The boys and ladies on the hill cant seem to move the needle - so the American people are looking elsewhere.
BTW, I'd also recommend you do a little bit of independent research on the issues. If you'd like I'd be happy to point you to some resources that do their best to eliminate bias and stick to the facts. You seem to have a lot of interest in this (and that's exciting), I just think you'd be better off with more detail and less pluralities.
