In Florida, the figures show that, in counties with 1 type of voting machine, voters with no Dem. or Rep. party affiliation appeared to split their votes roughly 50/50 between Bush and Kerry, which was to be expected; yet in counties with another type of voting machine, unaffiliated voters seemed to vote nearly 100% for Bush! Why did Florida voters with 1 type of machine vote 1 way, and voters with a different machine vote another?
Click here for a table that shows, county by county, how many registered Republicans there were (the vast majority of whom, polls and common sense tell us, would vote for Bush), how many registered Democrats there were (likewise for Kerry), and what percentage of registered voters turned out to vote (we can reasonably assume a roughly equivalent percentage of each party's base came out to vote). From those figures, they arrive at an "expected" minimum vote for each candidate. However, since many more people vote besides those who are registered Democrats or Republicans (i.e. Independents, unaffiliated, or members of some other party), the actual vote for each candidate is naturally going to be higher than the "expected" figure which is a projection based only on registered Democrats and Republicans. The table also then shows the actual vote, as of 98.6% of the vote tallied.
Some Florida counties used an "E-Touch" voting machine, and some used an "optical scan" machine. Let's look at these two groups:
