They want to manipulate the political process with anonymity using hundreds of millions of dollars. The Right wing's perspective is that I have exactly the same right to contribute hundreds of millions of dollars the same as the Koch's do. That makes exactly as much sense as me saying that the Koch brothers have the same right to sleep under a bridge as I or anyone else does. However, in the world we actually live in, I am about as likely to contribute hundreds of millions of dollars to political organizations as the Koch brothers are likely to sleep under a bridge tonight.
And just what are they doing that Soros, Steyer, et al are not also doing? And, BTW, they are not the most partisan Republican donators. Not even in the top 10.
