Here’s the headline at Mother Jones: “Birther John Philip Sousa IV Wants a Tea Party Darling to Run for President.” Mr. Sousa is, it seems, a disciple of Donald Trump, saying in an interview with Tim Murphy,
I mean, can you unequivocally say that Obama was born in the United States? I can’t. … I don’t trust [the documentation]. I don’t distrust it. I don’t know.
The Obama Conspiracy Theories Glossary defines “birther” as “someone who believes Barack Obama is not eligible to be President of the United States by reason of the facts of his birth.” Sousa doesn’t make himself a birther by that definition, but the way such statements are usually understood, his meaning is probably closer to “I don’t think Obama’s eligible to be President, but I’m not willing to commit myself on the record (wink, wink, nudge, nudge, say no more).”
So I am not going to criticize Andy Kroll’s characterization of Sousa as a birther, any more than I would criticize someone who called Donald Trump a birther.
