The Biden White House criticized Venezuela’s President Nicolas Maduro on Tuesday for barring the leading opposition candidate from his country’s upcoming elections — after Democrats tried to do the same to Donald Trump. Maria Corina Machado, 56, won the opposition primary in Venezuela last year and has been favored in the polls to beat Maduro in the July elections, possibly putting an end to the authoritarian rule of Hugo Chávez’s successor. But the Maduro regime blocked the Democratic Unitary Platform (PUD) opposition coalition from registering its candidate by midnight early Tuesday. Machado’s chosen successor, Dr. Corina Yoris, was also blocked.
