What do the numbers say? Here is U.S. foreign assistance appropriations for Ghana from 2006 to 2012:
Aid appears to be higher during the Obama administration. (The Census data suggest annual foreign aid of under $100 million a year for the earlier years of the Bush administration.)
But wait-- how much of the Obama spending is actually the result of the MCC compact signed under Bush? Although MCC spending isn't trivial-- $457 million for the period-- USAID spending is still much higher, and over half of the MCC appropriations were in 2006. By my reading, Ghana was better off, in terms of simple U.S. dollar aid receipts, under Obama.
