Giuliani vs. ClintonAs of October 2007 there are:Toss-Up: 11 states (132 EV)Lean Clinton: 14 states (220 EV)Lean Giuliani: 8 states (96 EV)Not yet polled: 17 states + DC (90 EV)Explanation:I´m using the latest Giuliani vs. Clinton poll in each state. A lead of 5% or less is considered a "Toss-Up", a lead of 5% or more is considered as "Lean".
Other candidates are not included, because A) there are not enough state polls for other matchups and B) Clinton and Giuliani already have about 100% name recognition, whereas a Clinton vs. Romney map would look freakishly red.
