Two Scenarios For A Last-Minute Iowa GOP Surge

   With Thursday looming, here's what could happen in the GOP race to tilt things one way or the other:

    Romney: The constant negative attacks keep working and with a superior organization, Romney grinds out a victory, with McCain and Thompson cutting into Huckabee's potential totals.
    Huckabee: Many of Huckabee's supporters are evangelical Christians and first-time voters -- under the radar so to speak -- and so they weren't picked up as much by pollsters nor were they swayed by the negative attacks all that much either. Any Thompson or McCain gains come mostly at the expense of Romney.

    Again, it's not a prediction but the hunch here is that of the two scenarios, the Huckabee one is likelier.
