I'm calling it: This is the year that Christmas officially enveloped Thanksgiving. With less than a week to go to Thanksgiving, the only channel I'm hearing more about Thanksgiving than Christmas is my family communications channels as we work out the plan for next week.
Next envelopment to watch out for: The Presidential campaign enveloping the mid-term elections. The 2008 Presidential campaign effectively started mere days after the 2006 midterms. I think it might take a couple more cycles before that fully overshadows the midterms, but it's going to get noisier.
