Remaking the Republicans

From a column by Rich Lowry, Ross Douthat and Reihan Salam in their book Grand New Party propose several changes to what the Republicans should do to attract more voters. The proposals outlined in the column are:

1. $5,000 per child tax credit
2. Subsidies for parents providing their own child care at home
3. Expanded transportation infrastructure to ease the suburban commute

#1 and #2 I have only a problem with when they turn into such a tax credit that parents get a bigger "refund" than they pay in taxes. #3 makes me uneasy when it's coming from Washington.

What are your thoughts?
