Perhaps no presidential battleground will test the leanings of critical independent voters more than the "Live Free or Die" state, the launching pad for Mitt Romney's White House bid.
President Barack Obama handily won New Hampshire four years ago. But Romney's ties run deep in the state, which has vacillated between Republicans and Democrats in recent years. Romney was governor of next-door Massachusetts.
Both campaigns are flooding the state with money and attention, suggesting more may be at stake than four electoral votes in a presidential contest each sides expects will be a nail-biter to the end.
Romney formally declared his candidacy on a New Hampshire farm one year ago, spends summer weekends in a vacation home on the state's largest lake and launches a six-state bus tour here Friday.
