In late October two fraternity brothers at the College of William and Mary picked their candidate for president. Their choice checked a lot of boxes. He had executive and legislative branch experience. And he had been a top surrogate on the 2012 campaign trail.

Their guy? Sen. Rob Portman (R-Ohio).

Trevor Parkes and Henry Longley, neither of them from Ohio, filed paperwork for the “Draft Rob Portman” super PAC and set up Facebook and Twitter accounts that consist mostly of sharing or retweeting Portman himself. They planned to really ramp up their efforts after this semester, they told Bloomberg in an interview last month.

“We just really, really admire Rob Portman and we think Senator Portman is exactly the kind of leader America is going to need in 2016,” Parkes told Bloomberg. Longley said the senator seemed “genuine” and “optimistic” about America’s future.

But they are too late.

The senator announced Tuesday morning that he will not run for the White House in 2016. “I don’t think I can run for president and be an effective senator at the same time,” Portman said in a statement.

Parkes and Longley did not immediately return a call for comment about what’s next for them. Their last Twitter activity was Monday — a retweet of a Portman tweet about his “bipartisan energy efficiency bill.”

Will the friends shift their allegiance to another candidate?

Or maybe they just need to adjust expectations. Portman didn’t say he wouldn’t accept the number 2 slot on the GOP ticket.
