Based on the average of all October polls, Kerry is currently leading in 7 states with 87 electoral votes. Bush is currently leading in 4 states with 48 electoral votes. In addition to these battleground states, The Times has Kerry favored in states with 190 electoral votes with Bush favored in states with 213 electoral votes. Adding these to the electoral votes of the battleground states in which Kerry and Bush now have the edge and you get the following: Kerry 277, Bush 261.
Obviously, neither candidate has a secure lead in the Electoral College right now--a switch of one or two states such as Ohio, Wisconsin, or Florida could change the picture considerably. But based on this analysis of recent polls in the battleground states, if either candidate has a slight edge, it's John Kerry. And that's without even factoring in the expected late movement of undecided voters to Kerry.
