Luckily, the Senate is stacked in their favor, and thanks to gerrymandering, they can lose the popular vote by an absurd percentage and still keep the House.
Dems winning the two party house vote 55-45 would probably be enough to flip it, and that's definitely possible. (2012 was only 51-49 D)
There is no such thing as a 55-45 two party house vote. Even the biggest waves in history (1994, 2006, and 2010) were only 7-8 points. The Republicans are virtually guaranteed control of Congress in 2019.
they are not guaranteed control. You get a popular vote win of 8 points nationwide for the House it is impossible for them to keep a majority.
