A former Democratic National Committee chairman says President Barack Obama and the party’s congressional leaders should immediately come up with a process to identify a potential successor candidate for Hillary Clinton for the off-chance a health emergency forces her out of the race. Fowler said he expects Clinton to fully recover from her bout with pneumonia, which forced her to leave a Sept. 11 memorial event early and cancel an early-week fundraising swing. But he said the Democratic Party would be mistaken to proceed without a contingency plan. The party's existing rules empower the DNC to name a replacement candidate but include few guidelines or parameters.
