Democrats are quietly airing concerns that battles with President Trump, including investigations of the president and his administration along with the noisy debate over impeachment, are overshadowing the party’s agenda, threatening its grip on the House in 2020.

That narrative has been fueled by Trump, who has used his Twitter feed and interviews to lambaste Democrats as the “Do Nothing Party,” when in fact they have spent the first five months of their House majority to tick through agenda items they highlighted in the midterm campaign, addressing matters from lowering health-care prices to political corruption to background checks for gun buyers.

But voters aren’t paying much attention, party leaders are finding, leading them to redouble their messaging efforts — including by placing a target on Senate Majority Leader Mitch McConnell (R-Ky.), who has blocked consideration of the Democratic bills.
