Same could be asked about Trump supporters.Also why do they keep arguing about Trumps impeachment when they say its a sure thing to help Trump?
False accusations or the inflation of minor issues have a way of backfiring. Democrats are enjoying a likely quick and short term drop in Trump’s popularity over the latest accusation, but this is likely at the longer term increase in Trump’s reelection prospects.
By the way, during the 2018 elections, Democrats Pelosi and Schumer both won their reelections with approval ratings below Trump. How does that happen?
