The 10 Most Vulnerable Governors in the Country

While the odds favor a Republican takeover of the U.S. Senate, the story is slightly different across the gubernatorial map. Democrats are optimistic they'll take back the governor's mansion in Pennsylvania, Maine and Kansas, while the margins remain close in a handful of other states.

Below, a look at the governors who look the most vulnerable with 30 days to go until Nov. 4. The list excludes close open-seat races in Arkansas, where former Rep. Asa Hutchinson (R) is favored to succeed retiring Gov. Mike Beebe (D), and in Arizona, where state Treasurer Doug Ducey (R) maintains a lead over former state Board of Regents member Fred DuVal (D).
