Not a valid poll. (Though many if not most polls are not valid).
I get your point, and I did vote.
Though like preaching to the choir, this is polling the choir if they believe in the God they are singing about. You have a good idea how the poll will come out.
It’s valid if you understand what it’s for.....and what it’s for is to measure the top candidates among the internet forum conservative voter. It’s not valid if you are measuring Jeb or Hillary - or Christie or some others - but it’s extremely valid to see how Cruz, Walker and Paul measure up. It’s valid to see if the huckatorum or santuckabee beast has support.
It’s also valid to see where people may be headed next...as the internet talk radio audience is the most informed audience, where they are can be somewhat of an indication as to where the others will land once they start paying attention.
I know polling.
