Let’s have a big round of applause for Trey Gowdy.

The 11 hours Hillary Clinton spent at the House Benghazi committee last month appears to have been time well spent: The Democratic front runner has significantly improved her standing among key groups of voters.

Among Democratic primary voters, 72% said they were now satisfied with Clinton’s responses to questions about how she handled the attack on the U.S. diplomatic compound in Benghazi, Libya, in 2012, according to the Wall Street Journal/NBC poll. That’s up from 58% before her testimony.

Clinton’s lead over Sen. Bernie Sanders of Vermont among primary voters also grew slightly, the poll found. It now stands at 62% to 31%

Clinton made progress as well among swing voters, the survey found. Before her testimony, 84% of swing voters had said they were not satisfied with her responses to questions about Benghazi. In the latest survey, only 40% said so.
