Can you explain to me what Iowa caucus is and why its so important? Does it only happen in Iowa? If so why? If not why is Iowa so important.
I get there is a hold up for some reason but have the results been announced and if so what does that mean for the winner?
I will probably have more questions but nothing is making any sense on my normal news sources, they just seem to think I should know what this is, however I have learnt that pigs outnumber humans 6 to 1 in Iowa, which is very important when I am trying to find out what an Iowa caucus is
