I would imagine that that billboard around Lubbock would be pretty much preaching to the choir, right?
Lubbock county results for the 2008 election are easily available.
Even though the overall result was 67.98% McCain/31.26% Obama, there are a lot of precincts that went significantly for Obama.
IOW, 30,486 people in that county still need a clue. 66,304 just needed a better candidate. (And the 644 that voted for Barr really, desperately needed a better candidate. Who the hell let Mr Patriot Act himself run as a Libertarian, anyway?)
