But if one party would like to restrict those donations but can't, and one party wants unlimited donations and is using their power to make that happen, why shouldn't we call them on it?

That doesn't make sense. In the meantime, its reasonable for everybody to operate under the rules as they are now.
I'm sure you and your party (and don't try to say you're an independent) would love it if the Dems decided to take no big bucks money, and therefore were outspent 10 -1 in every race, but as I often tell you you're not dealing with the Dems of the past anymore. There aren't any Russ Feingold's left who foolishly assume they'll be rewarded for abiding by voluntary campaign finance rules that they're opponents are laughing at.
One party voted to reverse Citizens United. The other party blocked the bill. Its not any more complicated than that.
