That's the way it should be? Donations to a candidate's reelection committee are for the benefit of that candidate and severely limited by law ($3300 per donor per candidate per election). Treating inter-committee transfers as something other than donations would allow trivial circumvention of the 'per candidate' restriction - just run a bunch of nobodies, fill their coffers, and then have them drop and transfer to a single candidate

I'll admit this is a bit silly in light of PAC/SuperPAC spending now, but we did have election spending rules at one point and this was one of them.
