Let’s start here with a caveat: House generic ballot polling from a year and a half before a general election should not be treated as predictive. The 2020 House election depends on a lot of factors that remain unknowable, most importantly the tone-setting effect of the presidential race, which at this point appears to be something of a 50-50 proposition.
That said, if you’re looking for signs of a growing backlash against the new Democratic-majority U.S. House of Representatives, you won’t find it in national generic ballot polling so far. CONT.
