Hillary was out and about in Chappaqua doing last minute Thanksgiving shopping today. She was greeted by signs of support and friendly neighbors, and she tweeted her holiday greetings to all.
Thank you for all you have done! We all hope you had a wonderful and warm Thanksgiving!
Apparently the mystery has been solved. According to this in the New York Daily News, the signs were the project of a six-year old named Liam who cried when Hillary lost and wanted to see lots of signs to cheer her up.
