Trump's approval rating among the youngest voters remains underwater, but the latest YouGov/ Economist poll, conducted between August 9-11, shows Trump's net approval rating at -28 (33 percent approve, 61 percent disapprove), a 10-point jump from last month when it was -38 (18 percent approved and 66 percent disapproved).

President Trump's approval ratings nationally are low, but in Indiana and about half the other states, more people approve than disapprove of him.
