Oh yeah....the 2012 REPUBLICAN Iowa caucus
In 2012, it was the Republican caucus that was a mess. Back then, Mitt Romney was named the winner of the caucuses by eight votes a narrow victory, yes, but still a victory for the favorite to be the Republican nominee.
Except eight days after that New Hampshire win, we found Romney actually finished second in Iowa. The Iowa GOP announced, 16 days after the caucuses, that Rick Santorum had actually finished first by 34 votes. But even that result was tinged by uncertainty:
Eventually, amid pressure, the party decided to just declare Santorum the winner in a statement released just before midnight on a Friday night prime news-dump time.
To clarify conflicting reports and to affirm the results released Jan. 18 by the Republican Party of Iowa, Chairman Matthew Strawn and the State Central Committee declared senator Rick Santorum the winner of the 2012 Iowa Caucus, the party wrote.
