2018 US House Election- How many US House seats Democrats will have after 2018?

Democrat Tim Walz has done a great job for the people of MN-1 since 2006, and could probably continue to be re-elected indefinitely. He has set his sights on the Minnesota governorship instead, though, and we'll probably lose the district as a result.

I certainly understand Walz's decision. He's a family man, and would probably love to work in-state, where he can spend more time with his family. Besides, holding a seat in the U.S. House, with its two-year election cycle and the resulting perpetual state of campaigning (and fund-raising), must wear a person down. Still, I wish he could have stuck it out in Congress, as the DFL party here in Minnesota has several other very good gubernatorial candidates

it won't matter much if the GOP maintains even a slim control.
I am ever amazed at the ability of Democrats to snatch defeat from the jaws of victory.
