Why wouldn’t it have been of interest to know whom the Coloradans preferred prior to a the CO delegate caucus?
Inquiring minds want to know?
Instead, we found out that the 65,000 or thereabouts caucus goers supported Cruz. That had impact on the delegate count. The opinion of Coloradans who decided not to caucus doesn't matter. It would be like polling the people in 2012 who stayed home and didn't vote for Romney or Obama. Mildly interesting, but 100% unimportant.
I’m WAY more bothered by the lack of polling in some states that haven’t voted yet. I try to model what might happen in the delegate count, but several states with primaries upcoming have either no polling data at all, or else very outdated data, in some cases several months old.
