Exactly! From the 2000 borough map of Alaska, way out in the western part of the state, Bush won all the boroughs out there, and they have high native populations. The only reason he won those was because of Ralph Nader.
Minor correction: That's a State House District map. There are no exact figures for boroughs (and now there aren't for State House Districts either). I did some sums etc a while back actually and concluded that Gore did win Bethel Census Area and that it was impossible to ascertain who won Wade Hampton Census Area (since postal votes were only allocated by House District.) It was also impossible to be make 100% sure that Bush won the gigantic, near-unpopulated Yukon-Koyukuk Census Area, although I'm personally sure he did.
Oh, and their Native populations are high indeed:
North Slope Borough 68%
Dillingham CA 70%
Yukon-Koyukuk CA 71%
Nome CA 75%
Bethel CA 82%
Northwest Arctic Borough 83%
Wade Hampton CA 93%
