Once again.... fuzzy thinking... What do you mean by "correct" (This is what you are not clear about)

fair? honest? duly recorded? your side wins? Puerto Ricans can vote? Dual citizens can vote? the idiots can't, the mentally incompetent don't vote? ONLY people who can make it to a polling place? slaves don't vote? woman don't vote? non property owners don't vote? uneducated don't vote? You must be able to read to vote? Or... the position you seem to fix on... must have a photo ID.

Some of my possible answers to your request of "correct" are fuzzy eg FAIR... others are specific eg woman can't vote! Some have been rectified and other issues... nominally rectified. (see voting rights act) All have to stand up to the test of... Is this a barrier to YOUR franchise to vote.

The problem you seem unwilling to address is that the gap between "correct" and "franchise to vote in a democracy by citizens" is enormous and the issue is... what are the details?.

I repeat... NO ONE in the debate is saying non citizens should have "no" barrier to voting. Lord knows... they can politic in elections just like citizens and hope to influence your vote. (see Russia and Israel, and many other countries)

The only completely accurate system with integrity would be for EVERY man woman and child in the country to have a single government issued ID card (aka passport) updated every XXX years and show that along with local address documentation to VOTE. This system eliminates the gap between "correct" and "actual citizens" voting

Short of that... what trade-offs do you want to make? and what set of facts supports the need for your system and would explain what you mean by "correct"?
