BAM! 
Justice Thomas nails it: 

"Thomas then caught her by surprise, asking whether a misdemeanor conviction of any other law 'suspends a constitutional right.'"

"Ms. Eisenstein, one question," Thomas said. "This is a misdemeanor violation. It suspends a constitutional right. Can you give me another area where a misdemeanor violation suspends a constitutional right?"
