As I said last week, Rush's Venus is in the quirky and rebellious Aquarius and carries some pretty heavy karma with it. Basically his mouth is compensating for a whole host of inadequacies.
President Clinton’s Venus is in its ruling sign - Libra - which increases his sexual appeal. He doesn't haven't to rely on rebellion he can rely on the sexual energy of Libra - and --oh boy is this a hoot ---his Venus is conjunct both Neptune and Venus! So he has a double dose of Venus energy - Venus is the sign of the woman - and of sexuality and of physical appeal. Add Neptune to the mix - with its air of unreality and well you can see the issues he had.
Two Venus placements in the first bring both of their people to some prominence but they don't yield the same results - it is all about the aspects they make with other planets.
