Is it true that Republicans oppose gun control while all or most Democrats favor gun control?

21. I think you have it confused with the Hughes Amendment

The aptly titled drug “czar” William Bennett—on his first day in office—convinced the Treasury Department to outlaw the import of several models of so-called “assault weapons.” The NRA, attempting to preserve a relationship with the White House, praised the “temporary” import moratorium as providing a cooling-off period for a rational discussion of the “assault weapon” issue.

But a few weeks later, President Bush dramatically expanded the import ban to cover many dozens of additional firearms models. Bush Press Secretary Marlin Fitzwater added that President Bush wished that he had the additional authority to simply outlaw the domestic manufacture of so-called “assault weapons.”
