Last round of primaries Tuesday includes N.H., Mass. contests

Tuesday features the last big round of primaries in this 2014 election season, with New Hampshire and Massachusetts the most closely watched contests.

In New Hampshire, former Sen. Scott Brown, who represented Massachusetts from 2010 to 2013, is expected to win a Republican Senate primary in his new state. Among his opponents is former Sen. Bob Smith of New Hampshire.

A WMUR/Granite State poll last month showed a close general election race between Brown and Sen. Jeanne Shaheen, D-N.H. who remains the favorite. Brown’s margin of victory will be closely watched Tuesday to see how much clout he has among Republicans, many of whom could be wary that he’s adopted their state.

Nearby, Rep. John Tierney, D-Mass., is viewed as having a tough re-nomination race. Seth Moulton has done well with an anti-incumbent campaign.
