But since it isn't, targeting one group and making sure they can't get that advantage while clearly giving it wholesale to their opposite number - do I really need to spell it out further? Isn't the advantage for "progressive" groups obvious? Isn't it obvious that the 2012 election was influenced greatly by the amount of money that Tax Exempt 501 groups - on the Left - could use, and that conservative groups like the Tea Party were hobbled? 

...Um, no.
No, it's not obvious at all. It is, in fact, directly contrary to every bit of credible evidence and testimony I've seen on the subject.
