President Donald Trump has faced a surge in Republican revolts over the past few weeks, but political analysts told Newsweek that does not necessarily mean his grip on the GOP is slipping. Chandler James, a political science assistant professor at the College of Arts and Sciences, said, “Over time for any president, their political capital and grip on their party, we would expect to diminish." And Republicans may also be thinking about a post-Trump presidency, in addition to the midterms, James said.
