Senate Republican candidates across battleground states either lead or are within or close to the margin of error in the hotly contested fight to control the Senate, according to several AARP polls released Thursday.

Eight Senate races serve as the most critical elections for Republican control of the Senate majority. The Senate Republicans running include:

AARP commissioned polls across 11 battleground states, surveying likely voters, especially those age 50 and older.

The polls found that many of the races for control of the U.S. Senate remain close as Senate Republicans play defense going into the November elections. The polls’ findings include:

The series of polls released by AARP show an upsurge for conservative candidates across the country.

Stephen Lawson, the campaign communications director for Loeffler, said in a statement on Thursday:

It’s clear what’s happening all over the state of Georgia: voters are hearing Senator Loeffler’s conservative message, and they’re responding with overwhelming support. And it’s no small wonder. Kelly has boldly supported President Trump, backed the blue, defended the 2nd Amendment, protected life, and stood up to the far Left. She is the political outsider and conservative businesswoman Georgians trust to represent their conservative values and deliver results – and with their ever-growing support, she’s heading for a big win in November.

Republicans control 53 seats in the Senate against 45 Democrats and two independents who caucus with Democrats. This means that Democrats need to gain a net four seats to retake the Senate.

As Senate Republican and Democrat candidates continue to vie for control of the Senate, Nancy LeaMond, an AARP executive vice president, said in a statement that the battle for the Senate will be a game of “inches.”

LeaMond said:

To borrow a phrase from Al Pacino in the football film Any Given Sunday, this year’s Presidential race is a game of inches. The election will be decided in a handful of battleground states, and AARP’s survey results show that either candidate can win. One thing that isn’t in doubt is that 50+ voters will cast the majority of ballots. So, candidates need to address their concerns if they want to get across the goal line.

AARP commissioned Fabrizio Ward and Hart Research to conduct the polls between August 30 and September 5. The polling firms surveyed 800 likely voters with an oversample of voters age 50 and older in each of the states. The margins of error are under four percentage points.
