Show me an audit of any U.S. election. Oh wait, we don't do those.
How many dead people in the US are receiving social security checks?
How many people that have been dead for 10 years are receiving social security checks?
If you don't have to present ID, how hard is it to say "I'm John Doe," when John Doe is your neighbor who doesn't vote?

Is it hard to get an ID? Is it expensive to get an ID? Do you need an ID to buy beer? Do you need an ID to board flight? Do you need an ID to complete any number of government related functions? What % of registered voters don't have an ID? What percentage of people that want to vote can't reasonably get an ID?
Don't be a fucking moron. It may be too late, in your case. The only reason to be against voter ID is to be for voter fraud.
