It’s not often that you catch a politician being so nakedly transparent about who he wants to face off against in an election. But wait until you see this:

A Trump-Sanders smoking gun.

South Carolina Trump activists in a much-promoted Facebook video: "We're asking South Carolina Republicans to show their support for President Trump by crossing over and voting in the Democratic primary for Senator Bernie Sanders." pic.twitter.com/FNqEUNXDWq — Bill Kristol (@BillKristol) February 26, 2020

You have to watch the full video to believe it.

Bernie Sanders is the preferred candidate of Donald Trump. He’s the preferred candidate of Vladimir Putin. If he remains the preferred candidate of Democratic voters, they can’t say they weren’t warned.
