I was struck recently by an op-ed in The Sun that proclaimed "Voting is an exercise in futility" (Oct. 17). I disagree. It can be an exercise in frustration, maybe, but not futility. I learned this in 1956, when I was seven years old. My grandmother lived with us and greatly admired President Eisenhower. During the Republican National Convention, while my sister and brother were out playing, I sat with her and watched the entire even — from gavel to gavel.
