On October 23, Montana Governor Brian Schweitzer, a Democrat who is pro-gun rights himself, was quoted in the Missoulian newspaper as saying that there is very little difference on policy concerning gun laws between Barack Obama and John McCain. He also suggests that voters who are most concerned to protect the rights of gun owners might wish to vote for Bob Barr.
Meanwhile, an MSU-Billings Poll released on October 23 gives these results. 400 voters were included in the poll: Obama 44.4%, McCain 40.2%, Ron Paul 4.2%, Barr 1.0%, Nader .7%, undecided 9.5%. See here for more details.
