True, but my point was that while he was elected Vice-President, he assassinated his way into the Presidency.
He seized power.
No he wasn't.
My history might be a little rusty but Hitler ran to become President coming second. His party however had enough seats in the Reichstag to prevent the other main party from forming a Government after several attempts by them he was appointed Chancellor by Hindenberg. Hindenberg being Head of State whilst the position of Chancellor was more akin to Head of Government.
He then used the fire at the Riechstag building to gain more power.
i.e. an argument could be that: It's a communist plot, we must have these powers to fight the communists."
so he used the democratic process until it served his needs, much like it would appear with Clark in B5.
Also, it's worth noting that as far as 99.99% of Earth citizens were concerned at the time, Clark didn't assassinate his way into office but became President through legitimate succession after the tragic accident aboard Earthforce One. Though in reality it was a coup d'état, very few were aware this was the case. It's not like he shot Santiago in public and declared himself king of the universe or anything.
No, he didn't literally put a gun to Santiago's head, but he WAS the mastermind behind the assassination, you can tell this with his line in that recording "I've wanted Santiago dead for so long.".
He was the mastermind, and as such, was directly responsible.
