Party chair says I'll move this thing to Halloween if that's what it takes' amid suggestion Democrats may go to Michigan first

Few in the US would suggest that the presidential election process should last even longer than it already does, but that is exactly what may happen if Republicans in Iowa follow through with a recent threat.

In an interview this week with NBC News, Iowa's Republican party chair said he would be prepared to move the state's caucuses - the process Iowa uses to identify its preferred presidential candidate - to Halloween" should Democrats shake up their primary schedule.
