If electricity is faster than the speed of sound why does it not make a sonic boom?

Ever hear thunder?
Okay, it’s not exactly the same thing – thunder is thermal expansion of air caused by the movement of large quantities of electricity, ie lightning. Sonic booms are the rapid displacement of air caused by solid objects moving through it at high speed – but both are waves created by the movement of their respective objects.
Sonic booms come from a large object moving at very high speeds through air. Lightning is actually very tiny and has very little mass, but the heat that it creates as it travels through air causes similar displacement and noise.
