3 Things I am looking to see from the Iowa Caucuses

My 3 things I am watching for:

1) Can Trump get more than 50%
2) Who gets 2nd between Haley and DeSantis? Also...if DeSantis finishes 3rd...is that the beginning of the end of his campaign?
3) Can Ramaswamy get the youth vote out and get into the double digits (10% or more) tonight?
