"Some nincompoop" must have been responsible for the cutoff in budget authority for the Conomic Development Administration, fumed Sen. Lowell Weicker (R-Conn.). The Northeast-Midwest Congressional Coalition points out that 90% of the EDA's loans and over 80% of its loan guarantees are issued to small firms. In fiscal 1980, 30% of these went to start-up companies. "I'm not going to have some nincompoop make such sweeping cuts after only a few weeks in office," Weicker said. Weicker was the only Republican, and 1 of only 10 senators, to vote against the Senate Budget Committee's recommendations. Aides to the senator say that although Weicker supports both the budget-cutting policy and the overall amount of the cuts, he can't endorse the "injudicious manner" in which the package was put together. Weicker wants a line-by-line, program-by-program analysis of what's good and what's bad in the proposed budget cuts.
