Have you seen the latest electoral maps?

Apparantly McCain has two more electoral votes than Obama now.This is such a close race.I look every few days,and the last time Obama was quite a bit ahead-now he is 2 below! I truly wonder if Obama is going to keep going downhill.Can anyone here give me there ideas about why this is happening?I have my own opinion,but would like to hear from others-no nastiness please-just opinions and facts.
