Even if you wanted to cross the aisle, it would be hard. If you work for Democrats, Republicans will not work with you. If you work for Republicans, Democrats will not work with you.
While highly political people I know don't seem to work in tech.
I mean, we’re doing anecdata here, but that doesn’t match my experience at all
So assuming it's possible in principle to be "not very political," the real question is how disengaged, uninformed, or lacking in understanding do you have to be for your statement to be true in itself, rather than a "quite political" statement. For myself, I think if someone is disengaged enough that they don't care who will become the next president, and there are no local political issues they will argue with someone about, they are "not very political."
Campaigns aren't wrong to be concerned about who has their data. There is good historical reason for them to be skeptical that security on your system will be strong enough to prevent customers from accessing other customer's data. https://time.com/4155185/bernie-sanders-hillary-clinton-data...
Now imagine getting buy-in for using customer data to improve your models.
I can't blame campaigns for being paranoid about vendors potentially going across the aisle. NationBuilder is one of the only big names I know that does it. They are in a unique and unenviable position given the death grip NGP VAN has, and they pay a big price for it on nearly every front.
If you take your example of NationBuilder, a company I know well as I led their European expansion, it only sold software not data. Unlike most American campaign software, NationBuilder does not sell data as part of their package. NationBuilder does not believe that you can create a sustainable and powerful community by using data that you have purchased, and thus only sells the platform.
So yes I agree with you that while campaigns can (and should) be paranoid about who has access to their data, and even how it is being used, this data brokerage model isn't the model that all companies adopt and it's a really important distinction to make.
While I am here, I will add the following, tech companies who want to democratise democracy (and I'm not saying that's the mission for everyone) and help lower the barrier to entry, cannot claim to do so if they alone decide who has access to these tools. Crucial decisions, such as which parties have access to the latest technology, should not be in the hands of a few tech titans of Silicon Valley - where the power they already wield is already unmeasurable.
All of the above is a fascinating and important debate and also a very American one. Campaigning and political technology is incredibly partisan in America, compared to Europe where what we fear most are monopolies.
I have no idea how to find out whether those tech stacks are indeed different. But if someone knows the answer I'd definitely find it instructive.
Whenever I've done calling or canvassing for progressive causes or democratic candidates we've used some version of NGP VAN (https://www.ngpvan.com/about).
I wouldn't be surprised if there are some cross-party solutions (especially the closer you get to core infrastructure—I'm sure both parties use AWS).
