Clinton, Trump clash over economy in final campaign stretch

With four days left in an often bitter contest that has tightened in the last week, each candidate attacked the other as unfit to be president in a late push for votes in battleground states that could decide the outcome in Tuesday's election. Clinton leads Trump by 5 percentage points, according to a Reuters/Ipsos tracking poll released on Friday, maintaining her advantage in the national survey even as the race tightens in several crucial swing states.
