Although "attempts to overtake and vote out of the current leadership" seems to indicate that the current leadership doesn´t support such "involvements". (By the way media articles before the election reported that neo-nazis were trying to infiltrate the "Linkspartei" too.)
But you should realize that people could make equally unfair comparisons about Schroeder. Like his "friendship" with Putin. Democracy in Russia anyone? Weapons sales to China? Are these pleasant involvements?
Why vote for a party that simply says that they´re opposed to something and wouldn´t try to fix it?
It´s an awful result! To repeat myself. :)
