Cruz is my first choice but if he is not the nominee I will not waste my vote by writing him in. You are free to do that but it is no different than if you had voted for Hillary, a total waste of a vote that might have kept her out.
I will donate to Cruz and vote for him in the primary, that is all I can do for him. Texas votes late in the primary process and by then the press has chosen our candidate for us usually.
As soon as Cruz announces his candidacy I will send him a check for $1000. How much are you sending?
I think next year the primary in Texas is being moved up to March 1st, which puts a very large state in the leading edge of primaries.
