The relevant interactive chart is here. My take home is that the NIH budget is relatively preserved even under the House plans for a continuing resolution (CR). NSF also seems to emerge from the President’s blueprint relatively OK.
That said, I am much more pessimistic about the longer term picture. Science R&D is the part of the budget termed discretionary by Congress–and until there’s a serious plan (that includes so-called mandatory spending–i.e. like Medicaid and Medicare) then discretionary spending is going to have to take the big hits in order to produce any significant results in the deficit.
