Interesting article in U.S. News & World Report:  How Giuliani Can Use Taxes to Win Over Abortion Foes, by James Pethokoukis:

Giuliani could use tax policy to appeal to social conservatives, say Republican insiders I’ve spoken with. So far on the tax issue, Giuliani has promised to permanently extend the 2001 and 2003 Bush tax cuts, and he spoke favorably about the idea of a flat tax after Steve Forbes joined his campaign. But he has not actually endorsed a flat tax or any other major tax reform. On his website and in campaign appearances, Giuliani has been touting himself as a "supply-sider." …

[B]y advocating a big increase in the child tax credit, as the social conservatives desire, and pushing for lower capital-gains and corporate taxes, the latter among the world’s highest–as the supply-siders want–Giuliani would have an economic platform that would tie together various strands of the GOP.
