The OK House of Representatives has 101 members. There are 62 Republicans and 39 Democrats. Only 1 Republican changed his vote. 14 Democrats backed away from Liberty.
While there are many Republican politicians who are just 'part of the machine' or RINOs or anti-freedom & big-business, this does support the general stereotype that Dems are anti-gun/anti-freedom, while (at least on RTKBA issues) Repubs are pro(-er) gun.
Those who say 'there are no differences between the parties' are either politically ignorant, intellectually dishonest, or trying to minimize the pushback against the Dems.
