Cruz will split the delegates in Texas and still lose much ground on Super Tuesday.
As long as it knocks Rubio out of the race.
It’s not about who wins TX, or by how much, except that if Rubio gets less than 20%, he gets no delegates. Assuming Cruz wins TX, the relevant question will be how many delegates Cruz and Rubio have respectively after Super Tuesday. If Cruz has significantly more than Rubio, the pressure on Rubio to drop out and be Cruz’ VP should be intense, especially since it does not appear he will win FL by himself.
