A new poll shows Hillary Clinton jumping to a 15-point lead against Donald Trump in the presidential race.

The poll, which comes after both political party conventions, shows Clinton beating Trump 48% to 33% across the country. The McClatchy-Marist poll shows Clinton with one of her largest leads of the race. The same poll showed Clinton leading Trump by only three percent last month.

A growing Clinton lead has been reflected in a variety of new polls.
