I have read before that in NH people are brought in from across the state line in MA and are allowed to vote. What is your opinion on this?
I have heard that too. It MAY have happened during the Hillary campaign. This is because we have same day registration. You have to show something like an electric bill that says you live at an address in NH. Then they probably will let you vote.
HOWEVER, IMHO this is mostly an URBAN LEGEND. What I understand that happened was that the Dems provided free buses from the campus of University of NH in Durham to the polling place in downtown Durham(off campus). A few miles away. So, students going to UNH could go vote much easier. Typically, college students tend to be more liberal than the average demographic. So, the more college students that vote. The better result typically for the Dems. They bused them a couple miles. Not from MA twenty miles or more south.
This is the ONLY factual event that I read about that actually took place here in NH. Obviously most college towns tend to be heavier Dems. Not only because of the student body population, but the liberal bias of the faculty. So, the more college student/faculty turnout, the better results for the Dems. Similar to us and the Absentee Military vote.
The main college towns are Durham(and surrounding towns), Keene(State), Plymouth(state) and Hanover(Dartmouth). The largest college in NH is the Southern NH U(SNHU). It is located on the north side of Manchester(the largest city). However, probably 95% of its students are online. Very few actually live on campus.
These college towns all tend to be heavy Dems/Liberals. Same with the bigger urban areas. The most conservative area of the state tends to be in the south. Many of which are former MA residents that may still work in MA. These people left MA in many cases because they hated the politics/taxes/etc.
They really get screwed on taxes because if they work in MA they pay a 5% income tax. IF they live in NH they pay on average the highest property taxes in the country. We have no income of sales tax here. Except an 8% rooms and meals tax. So, a lot of these former Massholes actually tend to be the most Libertarian. Fiscally conservative, socially liberal.
