The comparison is that if it’s indeed illegal, how is one that is clearly only directly benefiting the campaign a mere misdemeanor fine and the other a felony?
It's very likely Bragg's attempt to push this to a felony fails. It's just speculation (SINCE WE DON'T KNOW THE CHARGES) about what evidence is available and what people might be doing.
If Trump gets a $1000 fine for this, I feel like that's justice.
