Obama tried and, true to form, Obama failed. Obama was in power when the terrible Sandy Hook shooting took place (on the 14th of December 2012, 20 children were murdered by Adam Lanza). At that time, Obama had a majority in the Senate, which the Democrats maintained up to 2015. Obama could not get the legislation he proposed passed the Democrat-dominated Senate, let alone the Republican-dominated Representatives. It is true that Obama was a partisan and terrible at making deals with politicians: Obama preferred to moralize and lecture (good riddance to this useless US president – Obama made Jimmy Carter look competent). It is undeniable that plenty of Democrats support the Second Amendment, therefore it is naive to pretend that the Republicans and NRA are the only obstacles to reform.
