GREENSBORO, N.C. (Reuters) - Hillary Clinton got back on the campaign trail on Thursday after taking three days off for pneumonia, and the Democratic presidential candidate faced a more challenging political landscape, with Republican rival Donald Trump rising in opinion polls.
Senior Clinton aides said they always expected the race to the Nov. 8 election to be close. But it was clear from a raft of new polls that Trump had halted a summer swoon after taking steps to give a less freewheeling, more polished performance on the stump.
