See MnBlue, here. They link to Paul Thissen's
MPR Vote Tracker page, and what I noticed there is his support of the Iron Range Cancer Study funding; which fits his overall healthcare focal interest. That's the study that I feel is looking for a needle in a haystack, and is ignoring the haystack itself, in that cancer is showing up in miners exposed to the haystack [the taconite mineral], whether or not the needle [asbestos fiber] was present or absent. It seems the learned folks ignoring the haystack have some 'splaining to do.
