The C-SPAN web page has a link to Associated Press data that shows the percentage of the vote for each ballot-listed presidential candidate, in each county of the nation. Go to www.c-span.org and choose “featured topics”. Then choose “Campaign 2008”. The right side of the page has a map of the United States. Click on any state to get the percentages within that state. Click on the state again, and the map enlarges so one can then click on any county and get county percentages. The percentages are only one digit to the right of the decimal point.
