“What does Cruz gain by picking on an old guy he never served in the US Senate with and hasn’t done anything to derail Cruz?”
Dole IS the Establishment.
The primaries have come down to who is the more assured anti-establishmentarian.
Dole’s hatred is the PERFECT foil by which Cruz can define his position.
We'll agree to disagree. You think that. I'll repeat....what's the point of bringing all that up? Dole is an old guy who most voters know nothing about and don't care what he thinks.
