I've seen the numbers before in articles but stumbled across
this link that provided the historical numbers for several candidates. It provides some good news/bad news for most candidates. At this stage of the game, all candidates have more "will definitely vote against" than "vote for" numbers.
Mittens has a higher "definitely vote against" than any declared candidate and the highest negative net at -28%. Hillary has the second highest "definitely vote against" of a declared candidate. However, sher also has the highest "definitely vote for" giving her a -10% net which is second in least negative. She also has the lowest "depends" number at 20% indicating that more people have made up their mind about her. Obama has the least negative net at -6%.
Bill Richardson, who I personally am leaning towards, has next to last most negative net at -22 for the Democrats but he also has the highest "depends" number at 44% and lowest "definitely vote against" number at 30%. He has a smaller "definitely vote for" number tying Biden at 8%. It looks like Richardson has a big chance for improvement if he can repeat his strong performance in the last debate and give a similar performance in interviews.
Edwards is kind of in the middle of the pack with a -18% net. Biden has the worst net at -34%.
The good news from this poll is that the electorate is more favorable to our top two candidates than any Repug. Ghouliani is the top for the repugs in the poll with a net of -11% but his "definitely vote for" number is lower than Hillary or Obama.
