Corporations don't care what the base corporate tax rate is. They care about their effective tax rate, which is what they will actually pay in taxes after all deductions, credits, and deferrals are accounted for. Aside: I knew a guy who relied on wikipedia to give out tax advice. He was sued for malpractice and lost. He now owes his former clients $2 million (the amount of additional taxes they had to pay as a result of his erroneous advice).
