Personally, I don’t think anything will dissuade Cruz supporters from Cruz.
Same can be said of Trump supporters. Battle lines are drawn.
However, if Breitbart has information that needs the light of day, then it should get the light of day.
Put it out there.
I was a Cruz supporter for over 6 months. I donated $1,100 to his campaign, then I switched to Trump. Just saying.... ;>)
