WASHINGTON As Republicans assess the future of their party following their seventh popular vote loss in eight presidential elections, the biggest remaining unknown could become clear this week in a longtime Republican Party bastion that two months ago flipped to Democrat Joe Biden .

Republican losses in the pair of Georgia runoff elections Tuesday would throw control of the Senate to Democrats , giving them control of the White House and both chambers of Congress for the first time in a decade and adding an exclamation point to President Donald Trump s November loss.

Trump became just the fourth president in a century to fail to win reelection , and his refusal to concede and continued lies that Democrats stole it from him have put off the sort of analysis that the party undertook after losing to incumbent Barack Obama in 2012. Suddenly losing the Senate as well could heighten the partys sense of urgency.

Then all of a sudden theres some questioning, said one longtime Republican National Committee member, who spoke to HuffPost on condition of anonymity. The RNC member added that Trump would certainly get some of the blame: Hes inserted himself in the results.
