Statatics from Election Results

[Brian D]

Somewhat related: each election season there are published polls with a lot of questions, and you can often find the raw data and use linear algebra to discover how many people of each party were polled, and curious glitches/anomalies/flat-out-lies such as how many people of each party answered each question. In some polls you discover wildly fabricated results such as people switching parties between questions, or a negative number of voters of some party, etc.
