Then how do you rectify that opinion with Gore's poor showing in this poll? If you mean Gore with anyone but Hillary, I don't really buy it. Hillary vs. Bush gets her to about 40% as I recall, so she's not putting a drag on Gore (IMHO). Obviously this is only one poll, but I think Gore should be faring better given the sympathy factor and his time out of the spotlight (thereby helping his weaknesses fade from memory).
I used to think Gore might still be somewhat of a threat to Dubya, but not anymore. And his decision not to run seems to support that.
