Critique the legitimacy of the investigation into voter fraud claims made by Trump and compare it with investigations into collusion and obstruction of justice allegations.
This "investigation" of voter fraud is based upon only Trump's claim and has evidence that refutes him.  Collusion, obstruction, etc. investigations are based upon evidence and testimony from people _other_ than the ones who benefits.  This doesn't even get to considering Trump's reliability, or proven lack thereof.
I'd suggest you stop acting so foolish but you've already proven to intentionally push Trump's lies in the past so why would anyone expect you to start being reasonable now?
