Romney's track record on gun control is pretty well known: he supports a ban on "assault weapons".
Gingrich voted FOR the Lautenberg Amendment, which means if you were were convicted of a misdemeanor crime of "domestic violence" even before the passage of the act, you can't own a gun (ex post facto gun-grabbing). link
Ron Paul has consistently voted against gun control.
Why is this issue so absent from the discussion?
Every other election, gun control has been a (if not the) deal-breaker issue.
