Shelby was one of the first Senators to break against impeachment and he did so in a public way in early February of 1999.
He went on the Sunday morning talk show "This Week" and said that there were 10 to 15 Republican senators who would vote no on the perjury article.
It was a BS statement, and it had the potential of swaying other Republican senators to not vote for the article.
It was a "push" statement, I'll never forget it -- it's what I'm talking about.
If memory serves, he did vote to convict on one count and not on another which is still better than most.
Overall tho Shelby probably voted opposite the Clinton position on issues more often than just about any other Senator.
