Edwards got 46.6% not 47%. If you want to tack on the 0.8% the other Rat got, then you can get Edwards to 47.4%
The three GOP candidates received 27.4%, 23.6%, and 0.8% for a total of 51.8% There was also a Conservative Independent running who took 0.8%, so you can probably tack that on to the GOP total as well.
From experience, dems aren’t as likely to show up for a runoff.
How many GOP’ers will not turn out because their guy is no longer in the race?
