I missed this, what article or amendment to the constitution covers this notion?
My father enlisted at 17 for cripes sake. He could fight but not vote nor send campaign contributions? Come on man.
So, should we allow non-citizens to send money too?
They can't vote.
Campaign contributions about getting a message OUT.. and hoping that others will agree with your message.. it is NOT about buying votes.. so really I see no connection between "voting age" and campaign contributions.. unless of course you are trying to tell your kids that they are not allowed to have an OPINION or a MESSAGE until they are 18.... my 5yr old has MANY opinions.. some of which I hope she keeps for life, and some of which I hope she changes when she matures.....
IMHO, of course.
