I live in NC, but was concerned about issue of presidential vote not being covered under straight ticket vote (as it in NC). The ballot I downloaded from State BOE site for AL doesn't show a straight ticket option.
Meanwhile a lot of voters here turned out to defeat Bush, but weren't up to speed on three proposed state amendments, so some didn't vote on those.
Biggest sign of irregularity to my mind are as seen elsewhere too:
1. More votes than voters (this has to be checked at the county level and is legally public information, by precinct. If there are more total votes in any race than voters supposedly signed in, you should ask to see the voter books to verify number of voters and then challenge the results. (This happened in my county during Jesse Helms race in 1990 and incorrect result was ceritifed anyhow).
2. Discrepancies that are not credible in terms of number of total votes in (for instance) presidential, senate, or any other race compared to votes in congressional or other races. Only those who volunteered to work outside polls can verify whether voters were coming just to vote for Prez (for instance).
In Alabama Nov. 2004 election, the participation in senate and presidential races seems the same, more or less...But I don't have time to do the math on all the US House races... This is Nov. 9th, New York Times data.
