Not really, considering how it has been overblown, he wouldn't be able to get anything significant through Congress(even if it tipped to slightly Dem), and he wouldn't even try.
To me a lot has to do with other issues relating to personal freedom. If someone cannot grasp something as simple as the 2nd Amendment, I have a very hard time trusting them with much more complex issues. I find that using the Bill of Rights, especially the 1st and 2nd Amendment to be a good "litmus test" due to the simplicity and ease of understanding. Does that make any sense?
