No, you vote against him if that is what you fear. This fear-mongering though will not work on anyone who has seen the history of this play out over and over.So what, we should wait for them to pull the trigger instead of putting people into power that are explicitly against ending the DoE?
There are a handful of GOP holdouts that would not vote to dissolve the DoE, and that's why it hasn't gotten done.
Threats are still threats, acted on or not.
I am pointing out it is not really a valid fear based on history, but if you want to fear it go ahead and do so.
