During a normal White House race, the Alfred E. Smith Memorial Foundation Dinner allows the candidates to don formal attire, fire snappy one-liners and make subtle appeals to Catholic voters.

But nothing is normal in 2020. Thus, Joe Biden and President Donald Trump used this year's virtual dinner to preach to Catholic voters in swing states like Ohio, Pennsylvania, Michigan and Florida.

"Joe Biden's choice to run explicitly on the claim that he is a faithful Catholic squarely places on the table his claim to be a faithful Catholic," stressed legal scholar Robert P. George of Princeton University, writing on Facebook. He is a Catholic conservative who has also been a consistent critic of Trump.

“No way out of this, folks," he added. "It's not, or not just, Biden's critics who have raised the issue. It's the Biden campaign. …
