it has only been 3 times now.
Check your history. Thats the first direct answer.
your right it wasn’t 3 times.
OK is that answer good enough for you?
Now is the game up, no, is it over if he wanted to get enough delegates to the convention yes.
Does he and the establishment want a contested convention
yes
Is voting for cruz helping the establishment get their contested convention, yes.
Thus voting for cruz is voting for what the establishment wants.
Now uou will say , well the game is not over bla bla, OK so why did everyone else not give up, oh I know , no need for you t answer.
It is because they knew they had no chance of getting to the convention with enough delegates.
Bit like Kasich and cruz.
