The Democrats' whole campaign against President Trump is constructed around hyperbole and hypocrisy. While condemning Trump for needing to defend himself against Biden's witch hunts, the DNC has repeatedly said that they don't use PAC money for Biden's legal bills. Sadly and unsurprisingly, it turns out that the DNC has spent millions of dollars doing just that.
There is no comparison between the two campaigns. The Republican National Committee is now acting as the fundraising arm for Donald Trump's criminal defense. Biden does not use PAC money as essentially his personal checking account like Trump does. Unlike Trump, the DNC does not spend any of its grassroots supporters' money on legal fees. That's a huge difference.
Voters of all political persuasions are the losers here. Donor funds funneled through PACs and Super PACs have created an oligarchal, symbiotic relationship between both political parties and wealthy interests. All voters — both Republicans and Democrats — should be deeply concerned that special interest funding is incompatible with American democracy.
