One source is Jesse Benton and, reading between the lines, another key source appears to be Doug Stafford.
They are promoting the absurd idea that Ron was jealous of Rand and that is why Ron ran for president in 2012. From Coppins article:
[A]s I report in my new book, The Wilderness, Rand’s rise has indeed created some genuine intrafamily friction — and it started in the run-up to the 2012 GOP primaries.
One day early in 2011, Ron met with Jesse Benton — the young political strategist he shared with his son — to break the news that he wasn’t going to run for president again. …Benton was disappointed, but with Ron out of the picture, he decided it was time to start grooming Rand for a presidential run. He approached the younger Paul and pitched him on mounting an insurgent bid for the Republican nomination in 2012. He was adamant that Rand’s polish and pragmatism would make him a far more serious candidate than his dad ever was. Benton argued that, between the fiery base of supporters Ron had built up and the new voters Rand could attract, he would be a real threat to win the White House.
Rand ate it up. He told Benton to start putting out feelers for a 2012 bid, and the strategist moved quickly to schedule a trip to the early primary state of South Carolina. On March 23, 2011, Rand made a surprise appearance at the Charleston Meeting, a gathering of Palmetto State Republican elites, and news of the visit set off sirens in the political punditocracy. Rand fanned the speculation by announcing future trips to Iowa and New Hampshire as well. The buzz was building, the strategy was working, the wheels were in motion — and then, suddenly, it all came to a screeching halt.
A couple of days after Rand’s headline-grabbing South Carolina trip, Ron called up Benton. He had been giving some more thought to the idea of a 2012 presidential bid, and he’d changed his mind.
I’ve decided I’m going to run, Ron said. And I want you to manage my campaign.
Rand, it went without saying, would have to take a seat.
After that, the Paulites began to notice more signs of a growing divide between Ron and Rand. One of the most jarring episodes took place inside a green room at a 2012 Republican primary debate, when Sens. Jim DeMint and Lindsey Graham approached Ron and began effusively complimenting his son:
After 2012, many in the Pauls’ concentric inner circles felt compelled to pick sides — with the more pragmatic political pros signing on with Rand, and the true-believing purists sticking with Ron. The two camps have spent much of the past three years bitterly feuding behind the scenes (and trying to knife each other in interviews for my book). But those closest to the family say Rand genuinely admires his father and is anxious to make him proud by building on his legacy. And Ron?
One senior staffer in Rand’s Senate office told me that after years of closely observing the dynamic between the two men, he was left stupefied by Ron’s antagonism toward his son’s career.
“He should be proud of Rand, but he’s not,” the staffer said. “It’s a really weird relationship.”
The idea that Ron is jealous of Rand is absurd. It is completely out of character for the decent, principled gentleman that Ron is. Jesse, Stafford and Graham are spinning tall tales. Ron has not said a negative thing about Rand in public and the idea that Ron would express displeasure about Rand in front of a neocon like Graham is extremely unlikely.
As for Ron running in 2012, it proved the correct move as Ron expanded the libertarian movement exponentially with that run. It is Rand, Jesse and Stafford that have squandered the base that Ron handed off to them. In an election cycle that favors outsiders, Rand, Jesse, and Stafford, in one of the greatest miscalculations in political history, decided to cuddle up to the establishment, including Mitch McConnell, and apparently so cozy that even radical neocon Graham was singing his praises,
If anything, Ron has been too decent to his family, including the outer edges of his family. He should have dumped Jesse, who is married to his granddaughter, overboard a long time ago. Jesse has proven to be an incompetent strategist, managed to get himself embroiled in criminal charges that will result in a trial this February and was a key planner in Rand's disastrous plan to cuddle up to the establishment.
If anyone is pulling power plays, it is Jesse. There is no chance he would be anywhere around the Paul family if he hadn't married the boss' granddaughter.
The fact that he is backstabbing Ron to a reporter is disgusting enough, but to do it in such a vicious manner is over the top.
