Clinton, the favorite for the Democratic nomination, has seen her unfavorable rating rise across the U.S. with questions swirling about her use of a private email server during her time at the State Department. And, according to a new poll by Lansing-based EPIC-MRA done exclusively for the Free Press/WXYZ-TV, it’s no different in Michigan.

Some 55% of the 600 likely voters surveyed between last Tuesday and Saturday gave her an unfavorable rating, compared to 32% who viewed her favorably. Meanwhile, in head-to-head matchups with leading Republican candidates, she trailed former Florida Gov. Jeb Bush 45%-40% with 15% undecided, and barely led businessman Donald Trump 44%-42% with 14% undecided.

With 15 months to go until the election it’s too early to read too much into head-to-head results. But it’s still a notable turnaround for a candidate who in June led Bush in the same poll 40%-37%, and who counts among her top allies former Gov. Jennifer Granholm, whose Twitter photo shows her standing with the former first lady.
