It’s obvious that Tester is leading in this race, but I wouldn’t draw too many conclusions from polls of only one demographic, and we certainly can’t infer from this poll that Tester is ahead by double digits. Older voters in MT (and the Dakotas, for that matter) are definitely not as Republican-leaning as their counterparts in other Republican states which don’t have the same long Democratic tradition that Montana has. Unfortunately, there’s basically no exit poll data available for MT, but I’m pretty sure that they were Quist's second-best demographic group, actually.
It’s still not a good poll for Republicans by any means since these people are pretty reliable voters.
