"Unless there's something coming out of left field I don't see coming, it's his nomination if he wants it," Graham told guest host Pete Hegseth on "Hannity" Wednesday. "The Republican base appreciated him. We don't appreciate all the things he does sometimes. But from a policy point of view, he was the most successful president from a conservative's point of view since Ronald Reagan."
"[Trump] will be in the White House in 2024 if he runs a disciplined campaign," Graham said.
Republicans on Capitol Hill should talk about Trump's achievements during their elections, he added.
"Remember the Trump years on the border, ISIS, Afghanistan, … [and] energy independence," Graham said. "We should talk [about this] every day."
In addition to driving home the Democrats' failures, Graham continued, Republicans "need to be for things" such as securing the border, building the wall, and boosting America's energy independence.
"I'm looking for an America-first agenda led by Donald Trump that we can run on as a team and point out the flaws of the Biden agenda."
"We will clean their clock. In 1994, we won 73 seats to take over … the House for the first time in 40 years. If we play our cards right, we will exceed that."
Democrats are stuck between the radical left and the more moderate wing of their party, Graham said.
"The radical left has Biden in a box," Graham said.
In terms of national policies, Biden can't make a dent in cleaning up the border because the left won't allow him to, Graham said, adding that Biden has a conundrum with the left on expanding drilling for oil and natural gas for the same reason.
In terms of foreign policy, however, Graham said Biden is failing because he's Biden.
"When it comes to foreign policy, is not a left problem. He's just incompetent. He's been wrong on about everything for 40 years."
"There's a one-two punch brewing here. Radical Islam is on the rise and raging in Afghanistan, and you have an open southern border. If something doesn't change, 2022 could be the most dangerous year for America since 1939 and the world at large."
