On Youtube, I get non-stop anti-Braun ads from the Donnelly side. I have yet to see any pro-Braun ads on youtube - I only see them on broadcast tv. It's unlikely that Braun is not paying to run them on youtube.
I'm seeing both, but definitely more anti-Braun ads. Maybe 2/3 or 3/4 anti-Brawn adds, the rest being anti-Donnelly. VERY annoying.
