Perhaps Trump should spill the beans or shut up? The one thing that I know about ‘blow hards’ they threaten, but they never come through. If Trump has something then tell us and let us decide, otherwise empty threat make for empty suit.

He clearly referring to her being a bankster and a globalist. It's a matter of public record that anyone who reads here Wikipedia page will discover.

Trump knows by just hinting at "spilling the beans" will cause people to search.

It was a really dumb move by Cruz to allow his campaign surrogates to bring the spouses into the election.

BS! he said that he would spill the beans. It means just what it said. Your version is a bunch of double talk and you knew it when you wrote it. Such talk is beneath even Trump. If he has something then bring it out, but making empty threats is not the act of a strong person.

Trump knows by just hinting at “spilling the beans”

In Cruz circles that’s called an “attack” on Heidi.
Then they talk about how thin-skinned Trump is.

I wonder if Cruz’s operatives aren’t sitting on a snowflake college campus somewhere? Maybe Emory U?
