Someone who read the below post called and told me he didn't think the high percentage of undecideds for the Democratic primary field was a problem at all and suggested that John Edwards' poll numbers probably weren't very strong at this point ten years ago.
The earliest numbers for the 1998 Senate primary I could find were from a late March Winston-Salem Journal poll. It showed Edwards with 23%, D.G. Martin with 14%, and Ella Scarborough with 8%. 53% were still undecided.
I don't think Kay Hagan or Jim Neal is another John Edwards, but those numbers show that with the right amount of money, personality, and political fortune your stock can certainly rise quickly.
