Biden's lead is now 8.6 points in our national polling average. Similar to or very slightly higher than the past few weeks, when it was hovering around ~8.0. At least one more big poll (@ABC / WaPo) coming out before the conventions start tomorrow. https://t.co/cy51vc5isJ https://t.co/dcofxsDEnK — PolitiTweet.org
