White House Press Secretary Josh Earnest said Wednesday that Hillary Rodham Clinton’s strong showing at yesterday’s Democratic presidential debate would not affect Vice President Joseph R. Biden Jr.’s decision whether to run for president. “The dynamic for his decision hasn’t changed,” Earnest said, “because ultimately this is a decision he has to make based on a bunch of personal considerations, not based on the political standing of anybody else, let alone anybody else in the Democratic field.”
