Even Donald Trump’s national political director recognizes that his candidate’s ship is sinking.

According to Politico, three sources say that Jim Murphy, who has been the Republican nominee’s national political director since June, is taking a “step back” from Trump’s presidential campaign.

“I have not resigned,” Murphy told Politico, but he did say he would no longer play a role in the campaign due to “personal reasons.”

More from Politico:

“Several Trump aides said that Murphy has been conspicuously absent in recent days as the campaign mobilizes for the final push.

Since joining the Trump campaign in June, Murphy, a longtime party operative, has played a key role in setting up field programs in battleground states. He has emerged as a central point person between top Trump campaign officials and the Republican National Committee. Murphy also helped to oversee floor operations at the Republican National Convention in July.”

Now, hoping to preserve some sense of dignity, Murphy is calling it quits.

The news couldn’t come at a worse time for the Republican nominee, who is plummeting in recent national and statewide polling. It also comes on the heels of the third presidential debate, which surveys say Clinton won – again – very easily.

Murphy’s decision to distance himself from Trump’s dumpster fire may also be the result of a long list of recent events that have disqualified the GOP nominee, including the ‘Access Hollywood’ tape, Trump’s reckless whining about a rigged electoral process, and a growing number of women coming forward accusing him of groping them without their consent.

From the beginning, Trump’s campaign infrastructure – to the extent that it exists at all – was already lagging far behind Hillary Clinton’s operation. With less than three weeks until Election Day, losing his national political director is the latest sign that his campaign is coming apart at the seams.
