Over the last few days I did a lot of deep diving in Texas. Even though the election has not yet happened in 2012, it is important to analyze such large states in previous years for possible shenanigans.
I am suspecting that the brand of Central Tabulator may have something to do with the results. The Texas Secretary of State website provides a list of all equipment brands for all of Texas's 254 counties. You can download the PDF here:

I added a legend on the chart for the equipment used.
Look at the last color item: Z_equip:ES&S, Hart, etc.
It generally appears to me that charts from counties that use Hart equipment are flatter. Republican races with ES&S equipment have slopes.
I had done the overall Republican Presidential Primaries for Texas. Here's that chart again:
Here's a bunch of counties and different races:
Bexar County:
Dallas County: (2nd largest in Texas, Pop. 2,294,706)
Harris County (Largest in Texas: Pop. 3,693,050):
Jefferson County: (252,000 population)
Tarrant County:
Finally the General Election:
There's also a couple of democrat chart that I'm still working on that look strange, possibly a strong Black vote effect. I have to research that some more.
I'm particularly concerned about the last chart where McCain was flipping Obama. I've seen that in 2008 Ohio.
If we don't want riots in 2012, I think we better look into what's causing this.
There's plenty of strange charts here. Have at it.
