there could be nothing better than to see Bush3 and Cruz do battle. It would show clearly that the Republican party has had enough of the crazies. There couldn't be any backing down by either of them.
Sadly, Cruz knows now he's taken on more than he can chew and will keep his peepee in his pants for a while. Otherwise he would have answered to Bush's challenge by now.
Cruz has a lot to answer for when the nomination process gets going and there's going to be a whole bunch of candidates that are going to be willing to lay the GOP cards on the table and take him on. It's going to be great entertainment!
