Any race where a republican incumbent is polling within 5 of generic D with > 10% undecided I'd consider a tossup right now, frankly. Still good numbers for Republicans but that generic ballot question is a bit weak for Dems. Hard to see them winning the house with a lead of only 5 - though a final result of D +7-8 off of a D+5 baseline would hardly be inconsistent with 2017 results.
Democrats are leading the generic ballot by 10 points. Try again.
Misread the generic ballot question in Nj-2 as a national generic ballot question. No need to be a dick about it lol
Note: also meant Democrats when I typed Republicans there rip, should've been pretty clear from context though
