What is so great about this Biden controversy is that it shows voters if they vote for him there will be endless hearings on this stuff for years.
People that may have wanted to vote for Joe in order for the craziness of investigations and return to "normalcy" will have to think twice.
The Dems and media strategy have been to ramp it up to 100% negativity on Trump for 4 years so people will tire of the craziness and want change, less controversy.
