Ras has Obama +4 in CO. But look at what is reported in the internals:

-Among those who have already voted, Obama leads 57 to 42.

-Among those who have yet to vote, McCain leads by 11.

For those numbers to reconcile, 75% of CO would have to had voted already for Obama to be up 4. Surely that cannot be correct.

Can someone explain these numbers to me?

3. Ras Prediction for CO

Rasmussen Markets data gives Obama a 85.0 % chance of carrying Colorado on Election Day. At the time this poll was released, Colorado is rated “Leans Democrat” in the Rasmussen Reports Balance of Power Calculator. NOTE: Factors other than the latest Rasmussen Reports poll impact the Balance of Power ratings.

5. Colorado has vote by mail

so a very large portion of the voters may have already voted.

6. By my calculation

For this set of numbers to be self consistent 53% of those polled should have voted
