IMO: ANY good high power rifle or shotgun would serve the purpose of providing personal defense if what you're concerned with is your immediate family and household. You should have an adequate supply of ammunition on hand and Id recommend a supply of critical spare parts.
Beyond this point it would depend upon the situation.

IMO and I want to stress this is just my opinion; there are going to be "Issues" no matter who wins in November. What form these will take and the extent is anyone's guess at this time.
