COLLINS: My opponents say I've changed, I haven't but politics sure has. The non-stop false attacks against me began more than a year ago. Especially offensive are the outrageous attacks on my integrity. The suggestion that I traded my votes for campaign contributions is appalling. It never happened, not once, not ever. I was raised in Caribou by parents who taught me to be honest and to work hard. Mainers have entrusted me with their vote in the Senate and I've casted more than 7,000 times, never missing a single one. I will not back down from doing what I believe is right for Maine. I'm Susan Collins and I've approved this message.
