I knew Ron Silver was ill, but I had no idea it was this far along. Rest in peace, Ron. You’ll be missed.

Once a self-identified lifelong Democrat, Silver was a founding member of the liberal-leaning Creative Coalition in 1989. But he made a breathtaking political transformation, going from far left to radical right after the Sept. 11 terrorist attacks.

He spoke at the 2004 Republican National Convention in New York, enthusiastically backing a second term for President Bush.

“Twelve years ago I was here for the Democratic convention. I was on the platform committee. Zell Miller was the keynote speaker. A lot’s changed since then, I can tell you,” a chuckling Silver told The Washington Post.

“If you asked me on September 10, 2001, would I consider going to the Republican National Convention and speaking, I would have thought you were from another planet and didn’t know who I was.”
