A warning sign:

While voting was up by 18% in Colorado compared to 2008, the vote was down by about that amount in Minnesota and cut in half over 2008 in Missouri.

"A warning sign: While voting was up by 18% in Colorado compared to 2008, the vote was down by about that amount in Minnesota and cut in half over 2008 in Missouri."

That begs the question, does that include all primary voters or just GOP? In 2008, neither party had in incumbent candidate and both had active primaries. In 2012, only one does, so you would expect the overall voter count to drop by about 50%.
