Democratic Party officials in Iowa say they can’t do a recount of Monday’s razor-thin presidential caucus results between Hillary Clinton and Senator Bernie Sanders, even if they thought it was appropriate. And both candidates, in their debate later Thursday night, said it was no big deal. Just two-tenths of 1 percent separated Sanders and Clinton in the first nomination contest of the 2016 presidential campaign. The statewide caucus meetings included reports of chaos in precincts and coin flips to decide county delegates, raising questions about the final count’s accuracy . “People physically aligned in groups,” Sam Lau, the communications director for the Iowa Democratic Party, said in a statement. “There are no paper ballots to recount. Monday’s caucuses were a unique event that involved more than 171,000 Iowans and their neighbors at a specific time and place, and thus they cannot be re-created or recounted.”In other words, there are no hanging chads to recount.
