Kevin:

Did you look at package maptools?  I haven't myself delved into any of the other mapping 
packages, but I understand that maptools will handle shapefiles, which are generally 
freely available for the US states (and most countries).  See e.g.
http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html for a description, then
ftp://ftp2.census.gov/geo/pvs/tiger2010st/ to get the county numbers, then
ftp://ftp2.census.gov/geo/tiger/TIGER2010/COUNTY/2010/ to download the relevant 
shapefiles.

Hope this helps,
Ray Brownrigg
