Topic of the Day: Proposition 8

Should people outside a jurisdiction be allowed to make political contributions to sway a proposed ruling in that state?

In California, debate is raging over Proposition 8, the ballot initiative that would ban gay marriage by amending the state constitution. Support for the ban seems to be waning, but that's not keeping millions of dollars from flowing into the state supporting both side of the issue.  Apparently, even Brad Pitt is getting in on the game (but he lives in L.A when he's not out adopting children, right?)

Is that fair?
