Jill is hanging on like a dog with a bone.

Presidential historian Douglas Brinkley, author of “The Unfinished Presidency,” told CBS News’ “Face The Nation” on Sunday that Jill Biden is the driving force behind 81-year-old Joe Biden’s decision to run for reelection.

She likes power. She wants to stay. She wants some sense of revenge. She teaches at Virginia Community College. This milieu around our building here, this is her home. And the idea of relinquishing it all after you’ve taken the slings and arrows of the last years of attacks, and at the last minute, just when you get all the delegates you’re going to say, I’m going to open it up to a bunch of people — it’s very childish when you read those kind of reports.

“She is the vital part. Dr. Jill Biden is it,” he said. “You know, if you go back to 1952, Harry Truman could have run, and he didn’t. Why? Well, the Korean War and, you know, other reasons. But — but Bess wanted to go back to Independence [Missouri] — she didn’t like it in Washington.”

“If you cut to ’68, Lyndon Johnson was – quit in March of ’68 and people will say because of Walter Cronkite. No,” he continued. “The big thing was his health was bad, he had a bad heart, he was smoking, high blood pressure, tension, and Lady Bird Johnson didn’t want to stay in. And she wanted – let’s go back to Texas and convinced Johnson to step down.”

“That’s not the case with Jill Biden. She likes power. She wants to stay. She wants some sense of revenge,” he continued. “She teaches in Virginia Community College. This milieu around our building here, this is her home. And the idea of relinquishing it all after you’ve taken the slings and arrows of the last years of attacks, and at the last minute, just when you get all the delegates you’re going to say, I’m going to open it up to a bunch of people — it’s very childish when you read those kind of reports.”

It looks like elder abuse, Jill. And it looks like you’re addicted to the Biden graft and the mantle of protection the presidency throws over your ghastly family.
