The Dems do not have a "blocking minority in federal assemblies".  You haven't been to DailyKos in a while have you?  There is constant bewailing of this fact there.

Of course they prevented others from learning about the voting fraud.  Ask any American on the street about it now.  You will get a stare even blanker than the one you would get if you asked them the mathematical significance of PI.  They'll ask if your tinfoil hat is on too tight.

The fact is that they are a token opposition, no different than that in Belorussia.
