The chart above shows the average poll job approval of all presidents since World War II after they had been in office for 365 days. Note that Donald Trump has the lowest approval of any president, and the only one whose approval was below 40%. If he doesn't turn this around fairly quickly, he's going to have no coattails for Republicans to cling to in the elections later this year.
