Why does Bush keep vetoing bills that would help poor, sick children?

The Republican reasoning is that there are already too many entitlement programs and expanding this one would help some in the middle cl (*gasp* da horror!). They think they shouldn't have to pay for other people's medical expenses. This is brilliant reasoning considering they already pay for other people's medical bills when they show up in the ER with serious disease because they had no prior coverage and can't pay it now. It would be cheaper if the kids were covered beforehand so they can get screened and treated when the problem is small. But, what do I know?
