In Adams’ universe people realised early-on that under no circumstances should anyone capable of having themselves elected president actually be allowed to do the job. Presidents had too much fun being president to notice they didn’t have anyp power.
Zaphod even gave himself a lobotomy to become stupid enough to be president, unlike the current lot who don’t even have that going for them.

Zaphod was monstrously self-centred, and it could make him callous, but I don't think he was ever reported to experience hatred, or intentionally stoke it in others.
