At least 19 House districts in 12 states across the U.S. with hyper-partisan districts won't have incumbents — setting the stage for heavily partisan candidates.Guests: Axios' Stef Kight, Dave Lawler and Joann Muller. Plus, 3D printing…for cars.But first, today’s One Big Thing: the rise of hyper partisan politicians.If you think partisan politics is already a problem in this country, well, this year's midterms could see an even bigger slate of extreme candidates in at least 19 house districts in 12 states across the US, hyper-partisan districts won't have incumbents setting the stage for heavily partisan candidates. We're looking at both very progressive candidates who would kind of fall outside of what more moderate traditional Democrats have typically been for.And we're also looking at extreme right, kind of the Trumpsters who have questioned election results and have been on that extreme side of things coming from the right.NIALA: And so why are we seeing this veer to the edges of the both parties rather than candidates who were in the middle?STEF: You know, there's a lot of different reasons for why we're seeing this extreme partisanship and you can look at a lot of different things that have happened over the past few years. And especially drawing districts that creates safe districts for one party, making them extremely Republican or extremely Democrat.NIALA: Stef, I bet there are people who are listening to this who are kind of despairing because they think our politics are already too partisan and extreme. And while it's still early on in the process, we have seen that some of the maps that have come out of these states with independent commissions be a little bit more competitive, meaning that Republicans and Democrats both have to kind of fight over the seats compared to a republican or democratic controlled state where they're very clearly drawing lines to their own benefit.NIALA: Stef Kight is a politics reporter at Axios. So that is a sign that there are some slightly different views, uh, among our European allies of how we should handle the threat and what the coming weeks might hold.NIALA: Dave Lawler is Axios’ World Editor.We've been 3D printing things made out of plastic for a while now, and maybe you've heard us discuss 3D printing houses out of concrete, but now there's a new technology that's revolutionizing using metal in 3D printing.
