4,000 voters? Your information is horribly, horribly off. There are 167 voters comprising 2/3 of the BCS formula, plus the computers doing the final third.
If you look solely at numbers, and it's implied that #2 and #3 are in the same league, then yes your scenario makes sense. But there is a huge gap between 2 and 3. Top two teams are undefeated, and the third place team needed absolute miracles to win their final two games to finish with just one loss instead of three.
The SEC is not some end all of college football. It's the best conference, but not by much. Look no further than Missouri already in their title game. The same Missouri that hasn't won a conference title since the 60s. That powerhouse is suddenly tops of the conference. A one-loss SEC does not belong in the same conversation as an undefeated team from the other power conferences.
