There are 17 people on the Republican primary ticket.
A few of them are hobbyists who run every time just for the fuck of it. I think it costs $1k to register to get on the primary ballot and you need to get 1000 signatures, and to get on the general election ballot as an independent in November it is $250 and you need 3K signatures.
Anyway...Trump was about halfway down the list.
Today is the big day in NH and there is a lot of excitement. Looked like a big turnout at the polling place with folks waiting in line. At one point there were four new voters filling out registration paperwork at once (one of which being my 18y/o daughter).
We'll see how this turns out!
