Lindsey Graham says the Republicans will never win another presidential election if they don't 'do something' about mail-in voting

• The US will never again elect a Republican president unless lawmakers "do something" about mail-in voting, Senator Lindsey Graham said on Monday.
• Graham, a close ally of Trump, said that "we are going to lose the ability to elect a Republican in this country."
• The Trump campaign continues to push baseless allegations that Joe Biden benefitted from widespread voter fraud in the US election and has launched several lawsuits.
• Biden was confirmed the projected winner of the election over the weekend and held a victory rally.
• As expected, mail-in ballots in key battleground states leaned heavily in Biden's favour.

A senior Republican ally of Trump has warned that there will never be another Republican president if lawmakers don't "do something" about mail-in voting.

Lindsey Graham, the Senate Judiciary Committee chair who last week was re-elected the senator for South Carolina, told Fox News on Monday: "Networks that do polling that's way off — we're ought to call them into Congress and ask them how they do it.

"Mitch McConnell [Senate Majority Leader] and I need to come up with an oversight of mail-in balloting. If we don't do something about voting by mail, we are going to lose the ability to elect a Republican in this country."

In a different interview with Fox News last week, Graham urged Donald Trump not to concede the presidential election to Joe Biden, despite every media outlet confirming the latter as the projected winner, warning: "If Republicans don't challenge and change the US election system, there will never be another Republican president elected again."

Just a small handful of Republican lawmakers have publicly acknowledged Biden's projected victory.

McConnell on Monday backed President Trump's refusal to concede, telling the Senate that the defeated president was "100 per cent within his rights to look into allegations of irregularities."

He said: "Let's not have any lectures — no lectures — about how the president should immediately, cheerfully accept preliminary election results from the same characters who just spent four years refusing to accept the validity of the last election."

The Trump campaign continues to push allegations that Biden benefitted from widespread voter fraud, and has launched lawsuits in battleground states Arizona, Michigan, Arizona, and Pennsylvania. It was Biden's projected victory in Pennsylvania that led media outlets, including Business Insider, to call him as the winner of the election.

Biden, whose White House transition team has already got to work ahead of his inauguration in January, overtook Trump in several states during the counting process thanks to mail-in ballots that leaned heavily in his favour. Trump and his supporters have repeatedly described these votes as "illegal" without providing evidence.
