GOP Senate majority faces fresh uncertainty as 2 key races tighten days before midterms

Two of the country’s most watched Senate races, in Ohio and South Carolina, remain neck and neck with under a week to go until the Nov. 3 midterm elections, polling results released on Wednesday show.

In both states, the tight margins are a welcome sign for Democrats as they try to unseat a pair of Republican incumbents: Sen. Jon Husted, R-Ohio, and Sen. Darline Graham, R-S.C. Should both races go their way, Democrats would find themselves within striking distance of eliminating the current 53-seat Republican majority in the Senate.
