It's still general anxiety, which is just the lesser form of what eventually creates a panic attack and clearly not what he's referring to with a term like "amygdala hijack". I see no reason to get pedantic with it and create and entirely new sensationalist term to describe what is essentially a panic response. Also, in the example you've given most people have the ability actually think through the process logically and make a decision before they decide on something like voting. In a true "amygdala hijack" (like a panic attack) you don't get the chance to decide you just immediately respond with fight/flight. If you had the ability to think it through it would be a shit survival mechanism.
