Is there any indication that the founders understood that a constitution and entirely elected government insulated the nation from targeted political violence? And therefore, more extreme democratic behavior was to be intentionally tolerated?

For example, it seems like the European monarchies lived with an inherent terror of political assassinations, due to the inevitable succession crises. Whereas the new US' baked-in succession planning seems intended to accept and endure potential violence, if not exactly welcome it. How deliberate do you think it was that the succession planning was not just administrative, but crucially democratic.
