I strongly believe the discussion over format is just a clever distraction by their side. Pelosi doesn’t care about the format. It’s the timing they care about because Biden is in a nosedive and if Biden just makes it through without looking senile, he will change the momentum. (And if he truly bombs it, he can be swapped out.) There is no downside to a June debate from the Democrats’ POV and even just from the Biden team’s POV it’s a necessary move (despite the risk) given his polling numbers. And unfortunately, Trump agreed to it.
My “recommendation” is that pe-louse-i turn herself into GITMO for incarceration for her many (and ongoing) crimes.
