Really Bad Strategy

Biden had been hiding fairly successfully since he initially took on Trump to gain the nation's highest office. Joe had several excuses to avoid debate in this current cycle. He could have said "I will not lower the Presidency by engaging with a  common criminal", Biden could have declared "the nation's needs are too pressing for me to take time out to debate". He could have blurted out that he could not take time out from his oversight of "the Ukraine crisis" or the "terrible events in the Middle East", but he decided to walk right into a bear trap instead. Poor old man, woefully advised dementia sufferer, why did you take the bait?
