I guess my answer would be "no."
However, even though George Will is only the most intelligent human ever to live but not a public office holder, I was able, while attending UNC, to snag an illegal ticket to a speech which he gave at the business school. After the speech, I finally gathered enough courage to go up & ask him to autograph my copy of "The Leveling Wind." Well, he said "yes," I handed him the pen, he signed, and before he walked away he said something to me which totally changed my life: "Here's your pen back."
LOL---Hey! See, this wasn't a huge, 1000 seta event. It, by design, was a VERY small happening, and I was just lucky to even get INTO the place that night, though my tactics will remain a secret.
As for an elected official, back when I was a radical liberal and in charge of the [1992]Draft Mario Cuomo for President campaign, I semi-regularly spoke with liberal columnist, Joe Klein. Though he kindly refused to give me a direct phone number to his, Cuomo's, office, he did give me a special address, where I could write him & he would physically get it that day. So, after I wrote him a lengthy letter about how Bill Clinton was a scumbag- we in the Cuomo campaign knew about The Slick One before 99% of America- and how he, Mario, had to accept a draft at the convention. Well, he wrote me back a very kind & gracious letter, thanking me for all of my doomed hard work. Though after that I soon started to see the light & became a Gingrich- Republican, I still have it framed, on my wall, and still very proud that I got a personal letter from such an upstanding man, even though his politics are dead wrong.
So, I have never met a famous elected official, but I just thought those two stories were worth telling.
