SEABROOK, N.H., 5:19 a.m. — After months of campaigning and millions of dollars spent on television ads, primary day is finally here. And boy, is it a beauty.

Temperatures in Manchester are supposed to reach 60 degrees today, which should encourage turnout. New Hampshire Secretary of State William Gardner is predicting that a record 500,000 people out of the Granite State’s 830,000 registered voters will head to the polls today.
