Donald Trump mocks ‘low energy’ Jeb Bush in new Instagram video

Well, that was only a matter of time.

When a woman at a Jeb Bush rally in New Hampshire nodded off as the Florida governor spoke last Thursday, it was a made-for-Donald-Trump moment for the GOP front-runner, who has been blasting Bush as “low-energy.”

In the latest Instagram video from Trump, a narrator asks “Having trouble sleeping at night? Too much energy? Need some low energy?” Then, the video cuts to Bush explaining the intricacies of health savings accounts as the female supporter appears to nap in the background.

The tagline: “Jeb, for all your sleeping needs.”

Wake up Jeb supporters!
