A note about polls... that only just occurred to me "Hillary won the Popular Vote"
That is a fact we should EMBRACE, not shy away from.
The Generic Congressional polls are (at best) an indicator of NATIONAL preferences, and so akin the "The popular vote" in a Presidential election. Hillary's much referenced LEAD in the Popular vote did not count for a hill of beans in the final tally of Electoral College allocations. In these Congressional elections a nationwide party preference for Democrat is no doubt another manifestation of an abundance of Dem voters in selective locations (coastal elites) which are in effect "over kill" in a few States that the Dems have sewn up. Congressional seats are more akin to electoral College allocations.
2016 Presidential election:
Clinton (D) 65,853,514 votes 48.2%
Trump (R) 62,984,828 votes 46.1%
So taking the actual 2016 Election results as a "Generic Poll" the result shows
D +2.1 And yet the Electoral vote was:
Clinton (D) 232 43.1%
Trump (R) 306 56.9%
That is
R +13.8I realize that Electoral College is not same as Congressional seat distribution.. just an indicator, but the current advantage shown for Dems in Congressional Generic polls is unlikely to translate directly to seats gained in the House.
In fact.. what appears to be a BLUE WAVE In Congressional polls, might well translate into a RED WAVE on election day.

It seems to me that the DIMS will need a LARGE lead in the popular vote (generic polls) if they are to make any gains across individual States (blue wave).
My GUESS..... they need about D +10
