I suppose this is a little out of Date but three years ago i was in Washington and I met up with McCain as part of the course i was doing at Harvard I did post under a question about one the think tanks ( under heritage foundation but I got no response)

here is original post

"I went to the heritage foundation in washington DC yesterday
and heard Senator John McCain speak it was very interesting but I sure should have posted to mudcat first to see what questions I could have asked on your behalf. Cllr

PS Any folk music going on in washington tonight? "
