I think it is because his dad is famous and was inferring too much with his son and maybe his rehearsals and song choices maybe??I just heard something interesting on the radio about the 2 of them.
David A came into the competion and was very talnted and really hasn';t growen too much.
But with David C he has growen alot and is a lot more versatille with his song choices.Which I kind of have to agree with.David A is going to have the very young crowds voting for him and Maybe David C has the older groups of people voting for him.It should be interesting though.I do like David C though he is very humble about the whole thing.
