It is the Monday before the 2016 New Hampshire primary as I write this and the last opinion polls came out of the field yesterday. But the voting starts tomorrow (today, by the time you read this). So how accurate can Sunday’s poll be for predicting Tuesday’s vote? Possibly it will predict well, but things can change. Aside from some last minute SNAFU or attention-grabbing event, there is a sizable chunk of undecided or softly committed votes out there. So as the day unfolds at the polls, keep an eye on Google Trends, Facebook activity and Twitter activity for the candidates for any shifts in support.
