Ted Cruz gave a press conference a few minutes ago where he talked about his natural path to the nomination (plan A) and his path via a contested convention. In this video he explains why he believes he will win the contested convention and why RNC Chair Reince Priebus is wrong about the 2012 rules not applying to the 2016 convention.
Watch:
Cruz basically says that all the delegates elected to the convention will be mostly Trump and Cruz delegates and since both candidates have been clear that the rules shouldn’t be changed, the delegates will honor the candidates wishes and not change the rules.
