I created a mind map of the house race that are important. I referenced 538, because they were so wrong in 2016, but they have good polling data. Here is a 3 day link to my mind map of links https://spideroak.com/storage/JRXW4ZKNMNBW64TE/shared/534832-2-4337/Election2018.html?62dd7ad95524ddd704c20d93d7e654ab
It looks like we can't lose more than 20 seats. We'll probably pick up 2 seats, so we can only lose 22 other seats. Of those, 538 shows really bad polls in 13 of them, that leaves us only able to lose 9 of the remaining 31 that are in play. There are 17 that we are behind in the polls. WE NEED TO SAVE 8!
