Dante "GraniteProf" Scala has posted what you should watch for in tonight's results.
"If Mitt Romney pulls this out at the last minute, it's going to happen in the Interstate 93 corridor, home of many Massachusetts transplants."
"McCain's areas of strength form an arc around the I-93 corridor: Keene and Cheshire County; the Hanover/Lebanon area; Merrimack County, especially around Concord; and the Seacoast area."
"If Clinton carries Manchester by a wide margin, expect the results to be closer than expected."
"And if Obama carries Manchester, well, whoa Nelly! The rout is on."
