This is a bit dated interview of Senator Joe Haynes by Mary and Freddie on Liberadio from 3-12-07 but I first came upon it yesterday and it is fascinating. In it, Senator Haynes talks very candidly about why he changed his vote on an immigration bill. He says very frankly that he didn't want it used as a campaign issue against him. I believe he was talking about THIS vote. Clearly many Democrats and Republicans at all levels of government change their votes in this way but its rare they discuss it so openly. Also, a good lesson that vote records don't always tell the whole story.
You can listen to the entire interview HERE. Senator Haynes discusses Senator Kurita and many other issues.
