I'd also like to see a link to this report touting a statistically significant number of fraudulent voters. Anyway, requiring photo ID for out of state voters would not necessarily stop them from voting either. If I moved from MD but did not get a license in my new state, I could use my old MD license to vote in MD elections. Hell as a property owner in Baltimore, I should have that right!
We ALL see people in our states driving around with license plates from other states that clearly live permanently in our states. Those people likely don't have up to date driver's licenses either since that puts them in the system to alert the state about their cars.
