Instapundit’s Glenn Reynolds thinks so:

So in little more than 15 years, we’ve seen an amazing turnaround on an issue where the “establishment” side had broad support from politicians (in both parties, really) and almost universal support from the media. Gun control now is nearly dead as an issue, and the “establishment” view that the Second Amendment didn’t protect any sort of individual right, but merely a right of states to have national guards, did not get the support of a single Supreme Court justice.

So what’s the lesson for today? It’s that activism matters.

Another reason to celebrate on this July Fourth.
