The polls got the popular vote about right but got the states wrong.
Similarly, the polls may well be right about the overall national vote, but it’s meaningless. Many Democrat districts are routinely 80-20,90-10. That skews the national total. But when you go district by district,it’s a different picture.
The generic ballot has closed to a small margin. It’s +3 Democrat to +1 Republican, depending on the poll. That is the range where the Republicans are likely to hold the House.
The media doesn’t even see #WalkAway or #Blexit.
All the trend lines are moving towards the Republicans.
In several states — most — Republicans he a lead in early voting, which Democrats ALWAYS win. ALWAYS.
Pundits are hedging, and the Democrats are not acting confident.
Actually, that range is where Republicans usually gain seats. At least that has been my observation
