From the Wall Street Journal's James Taranto:
Hillary Clinton won yesterday's Democratic presidential primary in Michigan. This is not a very impressive accomplishment, seeing as how she beat nobody. In a dispute between Michigan and the national party over the date of the primary, Barack Obama and John Edwards sided with the party and pulled their names off the ballots, leaving only Mrs. Clinton and some negligible candidates, plus the option to vote "uncommitted"--an option of which far more voters availed themselves than Mrs. Clinton would have liked. The Detroit News reports that "[Mrs.] Clinton led Uncommitted 55%-40% with 97% of the vote counted Tuesday night." A 15-point margin of victory would be a landslide against an opponent. Against no one, it is a sign of both weakness and active opposition.
