I know that you’re crafting giant strawmen, and you’ll probably quote mine my post so you can demand that we be civil to the Leftists who want to literally kill us, but if you honestly seek clarification:
Disagreement with Trump, or conservatism, is not grounds for execution. It is never acceptable to terminate a candidate ourselves without a trial; extralegal remedies are never justified unless you are immediately endangered for your beliefs (and given that we are posting on a conservative website without fear of punishment at the moment, we are clearly not under immediate danger).
The assassin also does not understand that their methods will never be applied consistently, and thus would never lead to an effective justice system.
If politicians are convicted of treason (such as knowingly and deliberately sabotaging American security in the interest of illegals/Iranians/etc., or sabotaging an election for the sake of a party boss’s whim) by an impartial court, they should indeed be executed. The three GOP-e’s endorsement of Leftist murderers, private property violations, and 1st Amendment violations (among their other crimes) suggest that were they to be put on trial, they would be found guilty.
Politicians commit heinous actions precisely because they face no real consequences. Why wouldn’t a self-interested politician give out billions to his buddies at Solyndra to make nothing, or have millions appropriated for their own personal use, if they would never be punished for their actions? Would a minor fine or minor jail sentence really act as a deterrent against malicious actions?
Actually, looks like you've already CONDEMNED them WITHOUT a trial even though looking at their statements would tell you that they never "ENDORSED" the people you say they did.
