WASHINGTON (AP) — The largest Florida corporate donor to a super political action committee backing former Gov. Jeb Bush's presidential run is NextEra Energy Inc., the company that owns electric utility giant Florida Power & Light. Bush, a leading Republican contender, knows the company well. In 2009, more than two years after leaving office, he penned an opinion piece in the state capital's newspaper urging regulators to approve the utility's proposed rate increase for Florida customers. "With power, the cash registers open and close," Bush wrote in the op-ed, published in the Tallahassee Democrat.
