An Indication of How SC Votes Were Stolen From Ron Paul?

Writes a Ron Paul supporter:

Upon reviewing the Greenville County Precinct election vote data from the 2012, a disturbing pattern arose: Ron Paul averaged 24% in precincts where less than 250 people voted; he averaged less than 12 percent in precincts with more than 800. A spreadsheet was created to help me understand how this could be. Why was Ron Paul's percentage in large precincts half of that in small precincts?
