An unlikely backer has jumped aboard the Trump train, though it's not because she supports the New York businessman's campaign for president.

Ronna Romney McDaniel, the niece of 2012 Republican presidential nominee Mitt Romney and chair of the Michigan Republican Party, told Fox News late Friday that she has chosen to bind herself to Donald Trump going into the party's July convention because he won the April 8 primary and a majority of the 1.3 million voters who turned out at the polls.

"We want those voters engaged in the process, so as an RNC delegate, I chose to bind myself to the majority vote of Michigan," McDaniel said, adding that she will remain neutral as state party chairwoman.

In the case of a brokered convention that would give delegates a second vote in which they could switch candidates, McDaniel promised to stay aligned to Trump "to show them that the Republican Party is not disenfranchising their vote."

Her argument is similar to Trump's stance that voters who have already cast their pick for the nomination should not be abandoned in the case of a brokered convention.

McDaniel would not say if she personally supported Trump, but added despite what will happen at the convention, she will support the Republican come November.
