Should a photo ID be required for voting in the US?

Personally, I think it is a no-brainer. Yesterday, the New York Times was knocking the GOP for pushing photo ID requirement. Says it will discourage the young, poor and old from voting. I say gobbledygook - most of the young have them anyway (need them for bars and cars), poor and older people can get an ID from their state for free. Should slow down the voter fraud. I think that it is required in Canada. Thoughts?
