Jon Ralston's Interesting Prop Bet

From the Las Vegas Sun:  Lonely POTUS? Last time President Obama came calling, I wrote about how sad — and telling — it was that only Las Vegas Mayor Carolyn Goodman greeted him on the McCarran tarmac.
It was craven by many Democrats, who surely were frightened about photos being used by opponents but were only too happy to benefit from the cash he brought into the state.
I suggest this time the Nevada sports books put up a line on how many Democrats will appear in public with the president.
Let’s start the over/under at ... five.  http://www.lasvegassun.com/news/2012/jan/20/sandoval-loyalty-nevada-caucuses-republicans/?hpop
I think the bet should be 5 elected Democrats showing up to greet Obama. 
My bet then will will be under 5 Democrats who are in office who will appear in public with Obama while he is here.
