I would like to plot votes by precinct. Pretty simple, just color the precinct depending on its vote. MapPoint does not recognize a "Precinct" column coming from Excel, say. Are there precinct boundary files available anywhere? (I am interested in state of WA in particular).

More generally, is there any way boundary files for geographic entities other than the "Usual ones" like country, state, county, census track, city, etc, can be utilized in MapPoint? If so, please post information on where compatible format is defined and/or where such boundary files can be obtained.

Thank you. Tom
