Hillary Clinton received a boost among voters under 30 in key battleground states, according to a poll conducted after Monday’s first presidential debate.

A poll released Thursday by Public Policy Polling shows the Democratic presidential nominee with a large lead among voters under 30, a group she has struggled with, in Colorado, Florida, North Carolina, Pennsylvania, and Virginia.

In all five states, she has at least a 19-point edge among younger voters in the race against Republican rival Donald Trump:

Colorado: Clinton 50 percent, Trump 27 percent, Libertarian Party candidate Gary Johnson 15 percent, Green Party candidate Jill Stein 2 percent.

Florida: Clinton 54, Trump 28, Johnson 4, Stein 4.
