Those who are so vehement that Biden isn't up to the mark need to check themselves for prejudice against older people - ageism, and prejudice against people who are physically different than the so-called "norm", ie - stuttering. That one 's called ableism. People are judging solely by comparing Biden to a media-created image of the "perfect candidate", rather than on Biden's actual record and qualifications. Besides, this entire campaign is so similar to the well-documented and acknowledged Russian/Putin interference in the 2016 election that it feels like it has Putin's fingerprints all over it. Ask who would benefit the most if Biden is pressured to step down in the face of solid, grassroots support. If your answer is "Putin" , that should be a warning.
