Two key Republican senators have been re-elected to Congress.

Sen. Lindsey Graham (R-S.C.) and Sen. Mitch McConnell (R-Ky.) have been declared winners.

At the time of publication, more than 2.1 million votes had been counted in South Carolina. Graham had 55.1% and Democratic candidate Jaime Harrison had 43.6%, and Constitution Party candidate Bill Bledsoe had 1.3%, according to Google.

The GOP’s victory in South Carolina is especially significant since Harrison had “massively outspent” Graham, with $57 million in expenses declared for the third quarter alone.

“[This] suggests there are limits to the anti-Trump backlash in deep-red territory, though Democrats were never counting on winning a state that has not elected a new Democratic senator since 1966,” Bloomberg News congressional reporter Steven Dennis said.

Dennis speculated Graham overcame several “challenges” from more conservative candidates during the Republican primaries because he is widely perceived to be a close ally of President Donald Trump.

“Graham’s loyalty to the president solidified following the death of Sen. John McCain of Arizona, a longtime Graham friend, and Trump antagonist,” he said.

Meanwhile, in Kentucky, more than 2.1 million votes had been counted from which McConnell received 58.2%, Democratic candidate Amy McGrath 37.8%, and Libertarian Party candidate Brad Barron 4%, according to Google.

McConnell did not comment on his re-election results. He instead chose to reflect on the Senate’s successful appointment of Justice Amy Coney Barrett to the U.S. Supreme Court.

“[Barrett,] one of the most impressive nominees for public office in a generation, will serve for life on our highest court,” he said on Twitter.

He wished the new justice the best of luck for her new job and believes she will bring many good qualities to the nation’s highest court.

“Judge Barrett’s intellectual brilliance, integrity, and commitment to impartiality are above reproach,” he said on Twitter.

President Trump revealed he was quite pleased with the election results so far and is optimistic about his chances of winning another four years in the Oval Office.

“WE ARE LOOKING REALLY GOOD ALL OVER THE COUNTRY. THANK YOU!” he said on Twitter.

The president also thanked everyone across the nation who supported the 2020 Trump campaign from the “bottom of my heart.”

“You have been there from the beginning, and I will never let you down,” he said on Twitter. “Your hopes are my hopes, your dreams are my dreams, and your future is what I am fighting for every single day!”
