Santorum says the only reason you don't have a voter ID is you want to commit voter fraud.

23 million Americans do not have voter ID's, many of those do not have the method to get one, many elderly poor were born at home on the farm without doctors and with parents that saw no reason to tell the courthouse of a birth, so have no birth certificate, no proof of anything.  Another group like a Texas women who was robbed lost her birth certificate and will have a hard time getting it replaced with no documentation available, born out of state, plus a lengthy wait and fees to apply.  
This lady, and the old black women who worked in the Tennessee state house say this is worse than Jim Crow.  I don't know, but they must have a good idea.  Anyhow, according to Rick Santorum, these two old women are threatening America if they try to vote.   1 in 10 voter age Americans do not yet have the ID, I fear, and the GOP hope, that most will not be able to or ever get around to getting those ID's.

Poll Taxes and Jim Crow may be the only hope for Republicans, and I'd say they have it under control.
