When you get tapped along, it'll make your covfefe hamberders yippy.

“Tapping me along” made me imagine someone tapping a golf ball. Nudging it, but not making a big swing, it could be indicative of a subtle influence.

Trump may not know a lot about a lot, but he spends enough time golfing to potentially use a metaphor from it. On the other hand, I’ve never golfed (except the mini kind), so I could be way off.

Ever see a really well trained dog where all you have to do is tap the spot beside you and they bound over to you and dutifully sit in that spot?

I think maybe he meant "nudging me along"? I imagine Putin there at every step, reassuring Trump that he should just wait and see, that he'll do all work and make Trump look like the big man who negotiated a historic peace deal.

No peace deal means no publicity for the peace deal, so now Trump is getting worried because he tanked the global economy with nothing to show for it.
