Call it the "hot rock plan."

Senate Majority Leader Mitch McConnell has prepared an alternate plan to run Republican Senate candidates separately from Donald Trump, should he be the GOP presidential nominee, according to a report.

"We'll drop him like a hot rock" in the general election, McConnell has told associates of Trump, the New York Times reported Saturday, citing Senate sources. McConnell, a Kentucky senator, often uses such folksy phrases.

McConnell's plan assumes that Trump would lose a general election race badly and bring down with other Republican candidates on state ballots, threatening Republican's majority in the Senate. The party would encourage Republicans candidates to air ads distancing themselves from Trump in a bid to convince voters opposing the real estate developer to split their ballots and back GOP candidates further down the ballot.

McConnell has reminded senators of his own successful re-election campaign in Kentucky in 1996. He won despite Bill Clinton carrying the state on his way to an overwhelming reelection.

According to the report, in this scenario in which Trump defeat is clear, McConnell will pitch that a Republican Senate will remain a necessary check on a President Hillary Clinton.

Notably, McConnell is currently holding up the nomination of any Supreme Court justice, insisting that the choice should be made by the next president, who could be Trump.

The National Republican Senatorial Committee and McConnell's office did not immediately respond to requests for comment.
