Democratic and liberal aligned groups have put out 17
House polls taken in April or later. Republican aligned groups have put out 0. That's a very bad ratio for Republicans.
Interestingly, Republicans were the ones dominating the polling landscape in the first quarter of the year. From January through March, Republican and conservative groups released 10 polls compared with the Democrats' 2.
The April turning point lines up well with when the coronavirus pandemic became the headline story of the year. It's when President Donald Trump's approval rating started an almost
continuous decline that remains unabated.
In other words, it makes a lot of sense that Democrats started to dominate the House polling landscape in the past few months. They had a lot of good news for their side that they wanted out in the public. Republicans, meanwhile, were likely seeing numbers that wouldn't make them look good.
Now, you might be wondering whether statewide internal polling is showing the same thing. Presidential elections are mostly won on the state level, after all. Unfortunately, the presidential campaigns aren't putting out their own data, and partisan statewide polls have less of a chance to shape the narrative because there are so many public polls. Still, there are some outside groups that are releasing data, and we're largely seeing the same picture as the district data portrays.
Since April, Democratic or liberal groups have released 30 statewide polls in the presidential race. Republicans have put out a mere 13. That means the Democratic share of statewide internal polls has been 70%.
