I didn’t think Angle was an ideal candidate, but I think it’s clear from context that what she was saying was more along the lines of “Winning this election is important because things are so bad we’re a few awful bills away from folks starting to seriously consider revolution.”
One thing she was certainly not saying is that the Second Amendment legitimizes political assassinations. If only it were obvious to liberals that conservatives would not endorse, even in principle, the right of a John Wilkes Booth to afford himself of “Second Amendment remedy.”
That’s why the context of the Federalist is important here, and Rich does us a service by quoting it.
Also, every time Jefferson gets taken down a peg an angel gets its wings!
