That may sound promising to the law's detractors. But the thing is, the New Hampshire attorney general's office never supported Stand Your Ground to begin with. But it still passed. And the attorney general supported its repeal earlier this year. But that failed. The state's struggles are just one example of how steep of a climb it is to peel back Stand Your Ground nationally. As New Hampshire's Union Leader put it, the state will "have to endure without live performances from Stevie Wonder from now on." In Florida, meanwhile, opponents of the law don't seem to think they have a chance.

In Iowa, there's even one lawmaker who this week proposed to introduce Stand Your Ground to the state. A version of Stand Your Ground failed in 2012 after passing the House, but now it looks likely to return in the next legislative session. Iowa's not alone: A bill to expand Stand Your Ground was introduced recently in Ohio. On Wednesday, the bill's backer, state Rep. Terry Johnson, said that "you need to be able to defend yourself, you need to have a clear idea that this is a basic right that you can exercise at that moment, at that time."

At the federal level, Rep. Frederica Wilson, D-Fla., offered a resolution in February "urging the repeal of Stand Your Ground." And in 2012, Rep. Sheila Jackson Lee, D-Texas, submitted the Justice Exists For All of Us Act, which would have outlawed any state statutes that do "not impose a duty to retreat" before using force, outside of the realm of domestic abuse. That bill was eventually referred to committee, where it died at the end of the 112th Congress. The only real hope for critics of Stand Your Ground at the federal level looks to be from the Justice Department's investigation into the law, but we'll see how that goes.

Without a doubt, more states will look at their Stand Your Ground laws in the coming weeks. And the outrage and frustration over the death of Trayvon Martin, and the role Florida's law played in it, isn't likely to just disappear anytime soon. But right now, with Stand Your Ground firmly entrenched and with serious institutional and financial support from the likes of the National Rifle Association, the laws are so far winning out.
