We don’t know for sure yet who will be speaking at the Democratic National Convention in Charlotte, but there is at least one prominent Virginian who won’t be there — former Sen. John Warner.

The idea that the Virginia Republican might cross the aisle to appear with Democrats was floated Friday in a Politico article by Mike Allen. In the piece, which relies on unnamed Democratic sources and party planning documents, Allen writes: “Convention planners are considering featuring a centrist Republican leader on at least two of the three nights. ... And on the final night, Democrats may include a Republican leader — someone like former Sens. John Warner or Chuck Hagel — or a GOP woman.”

It’s not happening, Warner said Friday.

In an e-mail to Allen passed along by his office, Warner, now with the law firm Hogan Lovells, wrote: “Your excellent article of today, August 10th has surprisingly sparked some ’chatter’ that this old, humble soul might be asked to speak. As you know, since I retired I have followed a traditional Virginia ‘golden silence’ as regards politics at all levels. I shall continue!”

When he left the Senate in January 2009, Warner said, it marked the end of his active participation in politics. “Consequently, I will be watching both political conventions ‘from the sidelines’ hoping they will be constructive and informative for the general good of the public.”
