New polls show Republican Herschel Walker and incumbent Democrat Sen. Raphael Warnock neck and neck a week before the Georgia senate election.

Former President Donald Trump has endorsed Walker, a former NFL player who beat five challengers in the May primaries despite skipping several debates. His campaign has been fraught with controversy including his alleged payments for two women's abortions and his tax forms in which he lists Texas as his primary residence.

Warnock beat Republican Sen. Kelly Loeffler in a 2020 special election, giving Democrats a slight majority in the Senate for the past two years. He is now running for a full six-year term.

The runoff election comes after no one received 50% of the vote on Nov. 8.

A Nov. 8 polling average from RealClearPolitics shows Walker slightly ahead at 48.8% with Warnock at 47.4%.

A Nov. 26-27 Phillips Academy poll also showed Walker slightly ahead with a one-point lead over Warnock, while a FrederickPolls survey conducted from November 23-26 showed both candidates tied at 50 percent.

FrederickPolls show that independents favor Warnock over Walker 52% to 48%.

The Democrats already control 50 Senate seats following the Nov. 8 election results. The Democrats wouldn't need Vice President Kamala Harris' tie-breaking vote if Warnock wins. A Warnock win would also give Democrats an extra seat in Senate committees, reducing partisan gridlock.

"It's always better with 51, because we're in a situation where you don't have to have an even makeup of the committees," Biden said at a Nov. 13 press conference. "And so that's why it's important, mostly. But it's just simply better. The bigger the numbers, the better."
