Democrats seem to forget what happened in 2016 when Hillary raised DOUBLE that of Trump with $1.2B and he raised $600M.
Biden so far has about $710M and Trump has about the same as 2016 with $596M.
If anything, Democrats should be concerned that they're basically only raising half of what they did for Hillary in 2016.
Biden's campaign has to pay for the people to show up at his events and probably to buy votes and the dirty ballot harvesting. They are mafia.
