Most Dem voters do not look at any of this in any detail, they just listen to what the TV tells them.
Ask 100 Dems if they saw the video last election of Biden blackmailing Ukraine for $1B unless they fired the prosecutor investigating the energy company corruption including that of his son, Hunter. I would guess less than 3 would have seen it or even heard of it.
DO YOU THINK the Dems are suddenly not going to cheat in the key battleground states, this time?
