"It's just not true at all because that totally ignores the fact that once Kennedy got the nomination Byrd goes out and campaigns for John Kennedy," Corbin said.
Corbin point out Byrd campaigned for Kennedy and his running mate Lyndon Johnson in North Carolina and Texas, where there was a large Southern Baptist population.
"It was very important because the Southern Baptists in Texas were furious with LBJ for being on the ticket with John Kennedy," Corbin said. "Both John F. Kennedy and Lyndon Johnson would attribute their victories in North Carolina and Texas to Byrd's help."
Corbin's research shows John F. Kennedy and Robert C. Byrd had a good personal and working relationship during the President's tenure.
After Corbin delves into Byrd's childhood and rise in West Virginia politics in the book, he breaks the book into 11 more chapters, one for each President Byrd served with.
Corbin came up with the idea of dividing the chapters by presidential administration while sitting with Byrd on the Senate floor just before Byrd delivered a speech about serving for 50 years in the Senate.
"He and I started discussing the speech, looking over the speech, and we started discussing a lot of the historical events he'd been involved in," Corbin said. "We were talking about the cold war, Vietnam, civil rights, Watergate, the near impeachment of Richard Nixon, the impeachment of Bill Clinton."
Corbin said Byrd related each event to the president who was serving at the time and whether he worked or fought with that president. After that conversation it dawned on Corbin that no other senator had served with as many presidents as Byrd.
"A better way to put it, no other person has had so much impact on 11 U.S. presidents," Corbin said. "To put it in perspective, that's one fourth of the presidents in the history of the United States."
Corbin said four pillars were at the heart of everything Byrd did: God, country, the constitution and West Virginia. Corbin also wants the book to convey how well Byrd related to people in the state, which Corbin observed many times traveling around the with the senator in an RV called The Mountain Eagle.
"I saw the way he related to West Virginians, or the way West Virginians related to him is what was amazing," Corbin said. "People would just come up to him and actually they would hug us, his staffers, because we worked for Byrd.
"All over the state, wherever you went, it was just amazing to see the way people gravitated toward the man, just the way they admired him, and the emotional attachment as well as the political attachment."
Corbin hopes to eventually write a full biography about Sen. Byrd.
"The Last Great Senator: Robert C. Byrd's Encounters with 11 United States Presidents" is published by Potomac Books. It will be released next Friday.
Corbin is scheduled to appear at the West Virginia Book Festival in Charleston Oct. 13, and will speak at the Robert C. Byrd Center for Legislative Studies at Shepherd University on Oct. 16.
