The specific bill that got “killed” was not “Obama’s Bill”, but an improvement of the present back round checking. It also would have reaffirmed the ban on a registry of gun owners.
Overall the bill would have enhanced protection against tyranny. Criminal armed thugs have been used by many dictators to enforce their will.
Mitt Romney would have got that bill through. However, there is too much Obama phobia now for any gun measure. Obama’s statement in 2008 about “bitter people clinging to guns and religion” causes any gun related bill to be viewed as an attack on the rural culture.
