If you needed more proof that the current Republican Party's base is disconnected from reality and doesn't really care about our democracy, just look at this recent poll from the Washington Post. They write:
The survey interviewed a sample of 1,325 Americans from June 5 through 20. Respondents were recruited from the Qualtrics online panel who had previously reported identifying with or leaning toward one of the two major parties. We focus on the 650 respondents who identify with or lean toward the Republican Party. The sample has been weighted to match the population in terms of sex, age, race and education.
Nearly half of Republicans (47 percent) believe that Trump won the popular vote, which is similar to this finding. Larger fractions believe that millions of illegal immigrants voted (68 percent) and that voter fraud happens somewhat or very often (73 percent). Again, this is similar to previous polls.
Moreover, 52 percent said that they would support postponing the 2020 election, and 56 percent said they would do so if both Trump and Republicans in Congress proposed this.
