It also colonizes a large fraction of hospital workers so unless you injected it into the victim or got them to inhale a large number of aerosolized bacteria, it won't be effective. Assassination seems unlikely here to me. The presentation of sudden illness with multiple agents flu B, MRSA, and strep all at the same time is unusual. The presentation probably IS consistent with a sudden exposure to a very high number of infectious organisms into his lungs which could overwhelm the immune system and potentially lead to death. It wouldn't be impossible to orchestrate but it sounds difficult, finicky, unreliable, and tough to correctly execute without collateral damage. It would almost certainly require a state actor. It's also plausible he contracted influenza B and suffered from an opportunistic infection of the lungs. By Occam's razor I think the latter is quite a bit more likely.
