Personally I'm amazed anyone and especially Liberal/Democrats would even bring up "Approval Ratings" these days. The past 7 days I believe I have read well over a dozen polls, some of those included ABC, L.A. Times, Seattle Times, Bloomberg etc. which by in large with little variations.....
Trump 41%
Hillary 38%
O.J. Simpson 38% 
Congress 20%
Democrat Party 19% 

I can't remember for sure which liberal media poll it was, but they made a point out of Hillary and O.J. Simpson having the same approval ratings. Kinda tells a rather revealing picture of those who voted for Hillary I'd say.
