Sen. Lindsey Graham said Republicans are united and should be elated to cast their vote in the 2018 midterm elections or else they are “legally dead.”

According to Graham, R-S.C., Republicans have been brought together by the contentious confirmation process of now-Supreme Court Justice Brett Kavanaugh, and by a caravan of migrants from Central America on their way to the U.S.

"Kavanaugh and the caravan: If you're a Republican and you're not excited about voting, you're legally dead," Graham said in jest during an interview on Fox News Tuesday evening.

“Whether you were a Bush Republican, a Trump Republican, a vegetarian Republican, you were upset about what they were doing to Brett Kavanaugh,” Graham said. “They tried to destroy this man’s life to hold open the seat so they could fill it. They do not recognize President Trump won the election and chose a qualified person, and it is resonating all over this country. It is uniting Republicans and it has put Democrats on the defensive.”

Kavanaugh faced accusations of sexual misconduct from several women during his confirmation process, including from Christine Blasey Ford, of California, who alleged Kavanaugh forced himself upon her at a high school party in the 1980s. Kavanaugh denied all the allegations.

Ford's allegation was given to Senate Judiciary Committee ranking member Dianne Feinstein, D-Calif., before it became public, prompting suspicion among Republicans that Feinstein’s office leaked the allegations to the press even though Ford requested they remain confidential. Feinstein has denied her office was involved in leaking Ford’s allegations.

Graham said that ordeal, along with the caravan of thousands of migrants, has motivated Republicans to vote on Nov. 6 in the 2018 midterm elections. The comments come after the Trump administration announced Monday that 5,200 troops will be sent to the U.S.-Mexican border before the caravan arrives. A second migrant caravan has entered Mexico in recent days.

"Kavanaugh was an assault on everything we hold near and dear. ... Between the Kavanaugh debacle, a despicable character assassination, and a caravan trying to overrun our borders, it's been a nightmare for red state Democrats and it’s unified Republicans again," Graham said.
