'There aren't any earth-shattering events in July' -- the value of summertime polling - Bangor Daily News

The public polling available so far in Maine’s U.S. Senate race and other ballot contests has been infrequent — at least when compared to the daily polls that track movement in the presidential race.

But if there’s one thing to note about the handful of polls taking stock of Maine politics in recent months, it’s that they’ve been remarkably consistent, regardless of the pollster.

In the two days following last month’s primary, a survey done by the MassINC Polling Group for Boston public radio station WBUR found a wide lead for independent Angus King over Charlie Summers and Cynthia Dill, the former governor’s Republican and Democratic rivals for Maine’s open U.S. Senate seat.
