Gore, for running from the Clinton record. The 90s were a very prosperous time for the country, he had no REAL reason to distance himself from that. Clinton's infidelity wasn't going to sway very many people away from Gore. This should have been his map.
Besides, he had already tied himself to Clinton during the impeachment fiasco. Gore's obsequious comments towards Clinton at the end of it are what ensured I wasn't voting for him in 2000. I was supporting Bradley during the primaries, and then in the general I had a tough time choosing between Bush and Nader. In the end, I voted Nader, but if he hadn't been on the ballot I would have voted Bush.
