From my perspective the fake "Bernie Bernstein" calls claiming to be from the WP, the disproven claims of an audio tape of WP reporters offering 1000$(sp), the claims that Olde Hickory House didn't exist at the address which were disproven by newspaper ads and other evidence, the claims that the county was dry at the time Moore was alleged to have bought girls alcohol (it was not and the pizzeria actually served wine) -
All of these come together to be a flood of unvetted claims to keep Moore ahead until the election. It doesn't matter if they're disproven because many voters hear about them and take them as gospel without ever hearing the other side of the story.
