Democratic presidential nominee Hillary Clinton’s lead over Republican rival Donald Trump has narrowed to less than 3 percentage points, according to a Reuters/Ipsos opinion poll released on Friday.

Polls released just at the beginning of the week found that Clinton had a larger lead, ranging from 7% in a CBS poll to as high as 9% in CNN/ORC’s poll.

Friday’s poll found that about 42 percent of likely voters favored Clinton, to Trump’s 39 percent.

The poll, taken between July 31 and August 4 had a credibility interval of plus or minus 3 percentage points, meaning that the results suggest the race is roughly even.

Among registered voters over the same period, Clinton held a lead of five percentage points, down from eight percentage points on Monday, according to the poll.

The reasons behind the shift were unclear.

Clinton had pulled well ahead of Trump on the heels of the Democratic National Convention last week, where she became the first woman to accept the U.S. presidential nomination from a major political party.

Since then, Trump has engaged in a days-long feud with the family of an American soldier killed in Iraq and squabbled with the Republican leadership over his comments and leadership turmoil within his campaign.

Trump, however, has sought to refocus in recent days, noted Reuters. On Friday he announced his economic policy advisory team, said he would deliver an economic policy speech early next week, and was expected to endorse U.S. House of Representatives Speaker Paul Ryan who is seeking his 10th term in Congress.
