The statement 'A quick song for @MichelleObama #RunMichelleRun' along with a link to a website does not constitute public discourse. It appears to be a promotional or supportive message aimed at encouraging Michelle Obama to run for a political position, likely in a lighthearted or supportive manner. The hashtag and the mention of a song suggest a more conversational or promotional intent rather than substantive engagement with public issues or policies.
