No, it's that Cruz is running his campaign to appeal to a specific section of the electorate.
People don't like Cruz because of who he is, all in for TPA until it was safe:

Voted for cloture. TPA gave us the Iran deal, will give us Obamatrade.
And Cruz has no more experience than Rubio, both junior senators who sold out when needed.
OK. I see what you mean.
