I think this story raises an interesting question. Democrat political activists have taken to stalking Republican candidates with video cameras in an effort to find something that will look incriminating when replayed. I do not hold our professional politicians in particularly high regard. And I think our government employees, not just at the federal level but all the way down to building inspector, are far too entitled, and could stand to be taken down a peg in the social order. But this goes way WAY too far if you ask me.
Remember back when Democrats would hold up Obama's background as a "community organizer" as if it were a good thing? Now of course we all know what that is, so they've stopped talking about it. But back then the idea of being a professional political operative was considered a high moral calling - at least by the people who were doing it. But since then we've seen what these people actually do. None of them are altar boys and girls, but Democrat operatives are particularly nasty in their tactics. Lawfare is on the rise as a mechanism, and so too is every form of physical, mental and emotional intimidation.
Conservatives in the end , think politics really shouldn't be such a big part of people's lives. A conservative would be much happier with a part time government, and part time elected officials. But the left not only wants all those government officials to be full time jobs, but wants to make every full time job, at least in part, a part of the government. This is not a healthy thing, and doesn't lead to a healthy society - but they don't care about that. They have a singular vision to make politics a central concern in every decision making process. But that singular vision is putting pressure on their 'on the ground' activists to pull out all the stops and use 'whatever means necessary' to achieve their goals. The story above is evidence of that.
The pedestrian analyst would say that we should simply make professional political activism illegal, but that won't work. They will instead call themselves 'journalists' or 'researchers' and then you get into tricky legal ground when trying to limit them. Better would be to simply expose them for what they are, and encourage the American people to react to their over the top tactics the way they normally would - by rejecting them and their vision for America. They are scummy disreputable people, striving to achieve scummy disreputable goals, for scummy disreputable candidates. And there is a reason Al Capone didn't just run for governor of Illinois.
