Senate Minority Leader Mitch McConnell expressed concern Thursday about Republicans’ ability to take back the Senate during the upcoming November midterms, as polls show GOP candidates trailing Democrats in key races.

“I think there’s probably a greater likelihood the House flips than the Senate. Senate races are just different, they’re statewide, candidate quality has a lot to do with the outcome,” McConnell told reporters, according to Frank Thorp V of NBC News.

Although redistricting is expected to net Republicans the five seats necessary to take back the House of Representatives, elections analysts have downgraded the GOP’s chances at retaking the upper chamber amid a series of weak polls and anemic fundraising numbers.

Republicans received good news Wednesday with the release of an Emerson College poll showing JD Vance leading Rep. Tim Ryan by three points in Ohio. Ryan has significantly out-raised Vance, both in- and out-of-state, following a bruising seven-candidate GOP primary. Previous polls had shown Ryan leading by as few as three points and as many as eleven.
