Where have you been? Trump has mention ed this on more than one ocassion.
I have seen Trump warn against socialism, but I haven’t seen him say directly that even the mere nomination of Sanders could spook the markets. The point is to tie Bernie to a market correction before the media gins up another doom and gloom correction (”market experts warn of an impending recession”), thus defusing any IED the leftist media will attempt to detonate in the Sept/Oct time frame.
