Totally non shocking news.

[LWW]

I would have thought that if anyone really wanted to use this site's findings as a guide to which of the three sets of voters are generally most informed they ought to be looking at an average of the results recorded over at least several years.

Good idea ... so I added in the two you found and the results of the combined average was:

Republican voters were the most informed ... independent voters a close second ... and democrat voters the least informed.

Thanks for setting me straight on that.
