The questions are equivalent as originally written in the article:
One poll asked the following question:
“Should the voting age be lowered to sixteen?”
The second poll asked:
“Should sixteen and seventeen-year-olds be allowed to vote?”
When he later repeated the questions with percentage figures, he did in fact write what I quoted, which was:
"When asked if the voting age should be lowered 57% said no"
So within the context of the article, what I said was correct. But if you just read my comment and nothing else, you would be correct.
