WASHINGTON — To compete against Hillary Clinton, Donald Trump has finally conceded, he needs more than the bare-bones campaign team that led him to primary success. Yet he’s finding that many of the GOP’s most experienced political aides just aren’t willing to work for him.

From Texas to New Hampshire, well-respected members of the Republican Party’s professional class say they can’t look past their deep personal and professional reservations about the presumptive presidential nominee.

There are exceptions, but many operatives who best understand the mechanics of presidential politics fear that taking a Trump paycheck might stain their resumes, spook other clients and even cause problems at home.

“Right now I feel no obligation to lift a finger to help Donald Trump,” said Brent Swander, an Ohio-based operative who has coordinated nationwide logistics for Republican presidential campaigns dating back to George W. Bush.

“Everything that we’re taught as children — not to bully, not to demean, to treat others with respect — everything we’re taught as children is the exact opposite of what the Republican nominee is doing. How do you work for somebody like that? What would I tell my family?” Swander said.

Chris Wilson, a senior aide to Ted Cruz, said the Texas senator’s entire paid staff of more than 150 ignored encouragement from Trump’s team to apply for positions after he dropped out of the presidential race. Wilson said that even now, many unemployed Cruz aides are refusing to work for the man who called their former boss “Lyin’ Ted.”
