You can hold any opinion you like, but if you look at consistent Democratic turnout at near Presidential year numbers, and GOP turnout at midterm levels, and think that the GOP is on target to not lose the house, your opinion is based, at least partly, on a poor understanding of basic math.
Up until Kavanaugh, EVERY congressional district where Dems put up higher presidential year numbers, than Republican Mid Term numbers was in play... period. Democrats need 22 seats or something like that, and the number of districts where they outperform GOP midterm levels is far more than double that.. If not triple.
Not every district where dems are better in presidential years, that GOP in midterm will fall, but if you think GOP wins those 2 to 1 in the climate pre Kavanaugh, you are far more optimistic than math allows.
Its all moot at this point anyway as Kavanaugh completely shifted the playing field, with the GOP and Independents now ENGAGED an angry, there is no way the Dems take the house, and as I stated before, probably at or better than 50-50 right now that the GOP gains house seats.
