Turnout so far has been unusually low in almost all the early primary and caucus states. In part, that has been credited to low enthusiasm among Republicans for their options, including low enthusiasm for Romney, currently the favorite for the GOP nomination.
In a number of states, low turnout has been particularly pronounced in the districts that favor Romney.
Turnout won’t matter for the nomination battle, but keep an eye on it as an indicator for an enthusiasm issue the GOP nominee will have to address before November. Romney’s home state of Massachusetts is voting on Super Tuesday. He is expected to win there easily, but an unusually low turnout – below 15 or 20 percent – could be another warning sign that his supporters lack motivation to go to the polls.
