The latest polling data from Reuters shows a big move in the positive direction for Donald Trump in the days following the Orlando terrorist attack.

Prior to the tragedy in Florida, Hillary Clinton led Trump by almost 15 points in the Reuters tracking survey. But that lead has declined. Clinton now leads Trump by 10 points.

The Reuters survey accounts for a 5-day rolling average of interviews with 1,200 likely voters.

Prior to Omar Mateen killing 49 and injuring 53 people in Florida, terrorism was a distant third on the issues most important to voters, according to Reuters data. But in the wake of the Orlando nightmare, terrorism is the number one issue on voters’ minds. Support for a temporary ban on Muslims also increased. Today, a plurality of voters support a ban on Muslim immigration into the US.
