IIRC the polls I saw had Cruz winning in a range from 8-19%.
So his 13.2% is a respectable win.
But unless Cruz has a strategy that will give him 1237 on the first ballot this is won’t get him the nomination.
His new BFFs in the GOP establishment will stab him in the back as soon as he ceases to be useful in denying Trump 1237. Neither Cruz nor Trump have a prayer in an open convention. All hail President Ryan and his VP Rubio.
