It could all be a perfect storm for Rubio.
Blizzard comes early and scares away the new Trump voters.
On the fence Cruz supporters turned off by the mailer switch to Rubio.
Sadly probable, but what is Rubio’s ground game?
remember Santorum was in 3rd place and won before. but this would be even a larger longshot than that
With that said, OpnionSavvy and Emerson have poor track records. The most reputable polls like Selzer and PPP still have Trump winning with a good margin.
Very good points. That will make for some fireworks after Iowa!
