1. Trump - to win but by how much? Gerald Ford holds the record for a multi-candidate GOP contest with 45%, Trumpy must be aiming to top that to become the 'winningest'.
2. Nikki Haley - the anti-Trump poster girl. How big is that lane? 20%?
3. RDS - the end of the line for little Ronnie after the most spectacular political suicide note in modern times? 15%?
4. Vivek - does he have any actual support outside of social media? 5-10%?
