According to a nugget buried in this report from New York Times, the Republican National Committee (RNC) told staffers that they're free to leave if they can't line up behind presumptive nominee Donald Trump.
Republican elected officials, donors and strategists grappled uncomfortably on Wednesday with the inevitability of Donald J. Trump as their presidential nominee, an unexpectedly sudden denouement that left many in a state of political paralysis and others vowing to oppose the party’s new standard-bearer. [...]
For some in the party, the question of whether to embrace Mr. Trump is not merely an intellectual exercise. Some staff members at the Republican National Committee were told Wednesday that if they were unable to get behind the nominee, they should leave by the end of the week.
I don't think anyone would blame the RNC or any other Republican if they merely stayed on the sidelines and pursued their own priorities, but that doesn't appear to be the RNC's plan.
Chairman Reince Priebus's plan for the RNC is to go all-in and support Donald Trump, even going so far as to weed out anyone who has a shred of doubt about Trump.
The Republican party is Donald Trump's party now. Not Mitt Romney's. Not even George W Bush's party. It's the Trump party.
