They know that Trump will blow up their monopoly in DC.
Someone has to answer why Trump wouldn’t make a great President and someone from the establishment will. As soon as the establishment candidate says he will work with people from across the aisle, he loses the election right there.
And my not being 100% for Walker is purely selfish. Wisconsin still has a LOT to accomplish to make sure we don’t fall back into enemy hands after all the gains we’ve made.
There’s really no one on the bench to take over for him if he gains the Presidency.
How would Trump blow their monopoly when he is aprt of them and owned by them lock, stock, and barrel. He would represent total victory for the uniparty.
