It needs to be strong enough to render any liberal/DNC law suits or challenges mute from the get go.
It also needs to be large enough that Bush can claim a mandate without being laughed at. And it needs enough coat tails so he can get things through the Senate. He needs to win all the close Senate races in Bush Country; especially, Daschle must lose! Otherwise we'll see another 4 year stall and Hillary will run claiming Bush never got anything done. If Bush does this the Senate RHINOs and enough weak RAT Senators in Bush states will go along to end the stalemate. The current House, granting DeLay's firm hand in control, is adequate for Bush's needs, but a bigger cushion would be nice there too.
