Here's what Voldy himself has to say, from Chap. 33 of GoF: "But how 
to get at Harry Potter?  For he has been better protected than I 
think even he knows, protected in ways devised by Dumbledore long 
ago, when it fell to him to arrange the boy's future.  Dumbledore 
invoked an ancient magic, to ensure the boy's protection as long as 
he is in his relations' care.  Not even I can touch him there."

So, strangely enough, the gangly Petunia and the corpulent Dudley 
comprise a mighty fortress that can withstand the principalities and 
powers of the Dark Lord.
