Anti-Trump billionaires are funding ground operations in an increasing number of states to try to ensure the selection of national convention delegates who oppose Trump. The strategy is being executed by the anti-Trump Our Principles PAC, which has a stated goal of blocking the bombastic billionaire from clinching the GOP presidential nomination before the party’s convention in July.

But the PAC’s officials acknowledge that they likely won’t stop there and that they intend to keep up the pressure all the way through the end of July’s Republican National Convention, possibly including trying to steer the nomination to an alternative candidate…

In the coming weeks and even at the convention, Hubbard said, big donors and super PACs like Our Principles “can certainly try to influence people. I could call a delegate and say what I think, if they’d talk to me. I can buy a billboard. I can run ads. Why not?” Trump’s campaign will also be working to whip delegates, Hubbard noted, “and you’ll have other people trying to do the same thing. So fair is fair.”…

“We are going to take the fight to Cleveland,” [Tim Miller] said Monday. “Our role is going to be secondary to the campaigns, but to the extent that we can continue to communicate with the delegates about Donald Trump and why he’s not a viable general election candidate, we will,” he said, noting that the PAC is well-positioned to work with the delegates during a one-month break between the end of voting and the beginning of the convention.
