Joe, even in criticizing his former party, perpetuates the duality that limits our choices of leadership. With only two choices available to us in electing our leadership, the entirety of the positions on many issues must be considered when picking between them. This is how such extremes can co-exist with overwhelming and opposing public opinion on single issues.
Those positions are often shortened to hyperbolic rhetoric around freedom and economic opportunity, and people find themselves dissuaded from voting in their own best interests. To give in to one's better judgment on gun control means abandoning some pretty core ideologies everywhere else. This tragedy will wane in importance as other issues are forwarded by politicians and their compliant media to distract from it its center stage.
The 95% approval for reasonable legislation controlling gun proliferation will dissolve into the same philosophical arguments that divide us and we will be back to a dysfunctionally close margin determining who takes power over "every" facet of our lives. The only apparent unifying effect will be that neither of those choices will make life better for Americans, as they are both owned by their donors and kept in shackles by the interests that affect those donors.
