In Texas, a candidate's place on the ballot is determined by a ballot draw or drawing in each county. We have 8 candidates for POTUS on the ballot in Texas and we had my county's ballot draw last night. I got to draw for Hillary Clinton and she will be number one on the ballot in my county. I am now retiring from all future ballot draws.

On a serious note, there is some fun research that shows that position on the ballot can make a difference in some races where the candidates are not well known. That will not apply to this primary but still with 8 candidates on the March 1 primary ballot, it is nice to have Hillary Clinton at the top of the ballot.
