Doing some rough math, there were 3,612,258 registered births in the US in 1980, so about 9896 per day. I'm not sure the average voting age, and am too lazy to try to be more precise about average number of people with the same birthday.
The next question is around the number of people who share the same first, middle, and last name. I've met people with the same first-and-last name, but never first-middle-and-last, unless we assume both don't have middle-names.
In this case we're dealing with an even smaller population than the entire us population, just 2 states.
I'm too lazy and lack the data (on same name) to calculate precise numbers, but I'd be a little surprised if you could find 1000 matches that were different people.
