Poll: Obama expands lead on Romney
None
President Barack Obama expanded his lead over Republican challenger Mitt Romney to 6 percentage points in the White House race this month as voters became slightly more optimistic about the economy, a Reuters/Ipsos poll showed on Tuesday.
Four months before the Nov. 6 election, Obama leads Romney among registered voters 49% to 43%. Last month, Obama held a slim 1-point lead over the former Massachusetts governor. (Reuters)
