efficiency of charging electric car with gas generator?

I've heard it claimed that charging an EV with a gas generator is actually more efficient than driving a car powered by an internal combustion engine.

for the purposes of this discussion, lets define 'efficiency' as available energy in fuel vs energy provided to the wheels. Fluctuating costs of gasoline, generators and batteries might cause my brain to quit...

I can see how this might be true. As I understand it, gas generators tend to be more efficient because they have less moving parts (no transmission, no transfer case, much less friction loss) and they're designed with a much tighter operational range.

However, there is also energy that is inherently lost when being changed from one type to another, such as changing heat energy to pressure energy, pressure energy to mechanical energy, mechanical energy to electric energy and then back to mechanical energy again. Charging an EV with a gas generator adds adds 1 more energy conversion than driving a combustion engine car.

Has anyone actually done the math on this?

Dem politicians are trying to get rid of all gas cars, so they can fly more around in their private jets. So, rules for the rest of them, but not them!!!
