Joshua Green says that Jim Leach is a deficit hawk. The bar for Republicans to be "deficit hawks" is indeed low:
Pondering Orszag's Legacy: My dark horse candidate is Jim Leach, the former Republican congressman from Iowa, deficit hawk, and currently the head of the National Endowment for the Humanities. Putting a Republican like Leach in charge of OMB would be an intriguing move, since it would signal Obama's determination to cut the deficit and make it a bit harder for the GOP to criticize his efforts.
Leach voted for the 1981 and 2001 tax cuts, for the 2003 Medicare Part D expansion, and against the 1993 deficit reduction. His claims to be a deficit hawk rest on one vote and one vote only: his vote against the 2003 tax cut.
I wonder how much of this Joshua Green knows...
