Incoming Sen. Mitt Romney’s (R-UT) critical op-ed about President Donald Trump has renewed fears within the RNC of a moderate Republican mounting a primary challenge to Trump in 2020 and consideration of altering the rules to protect him.

According to a Wednesday Washington Examiner report, RNC committeeman Jevon Williams sounded the alarm in a mass email.

“Unfortunately, loopholes in the rules governing the 2020 re-nomination campaign are enabling these so-called Republicans to flirt with the possibility of contested primaries and caucuses,” Williams wrote.

“While President Trump would win re-nomination it wouldn’t come quick and it wouldn’t be inexpensive. Any contested re-nomination campaign—even a forlorn hope—would only help Democrats,” he continued. “Accordingly, I am asking for your support to take the unprecedented step of amending the rules to close loopholes in the re-nomination campaign…”

An RNC spokesperson did not immediately respond to a request for comment.

This is not the first time RNC members have toyed with the idea of manipulating the primary process to give Trump a buffer.

However, a complicating factor in this go-round is the RNC chairwoman, Ronna McDaniel’s, relationship to the man who caused the concern — McDaniel is Romney’s niece.

However, based on McDaniel’s Twitter reaction, she has already decided with whom her loyalty lies.
