Which do you think threatened Caesar rivals more his power or popularity?

Caesar's rivals were more threatened by his power than his popularity. His military successes and control over the Roman legions gave him significant political leverage, which undermined the traditional power of the Senate and other elites. While his popularity among the populace could rally support, it was his actual authority and the fear of his potential to disrupt the status quo that posed a greater threat to his rivals. Ultimately, it was this concentration of power that led to their conspiratorial actions against him.
