(The e-mail one. Not the Benghazi one.)
There's been a partisan split on the e-mail question for a long time, as we noted in our evaluation of Sanders's claim shortly after the debate. (And as is pretty obvious from the crowd reaction to Sanders's statement.) But new polling from Monmouth University specifically on the question of whether people are tired of it all suggests that independents agree: 59 percent of Americans are sick of the topic.
Notice that the options here aren't super clean. Given a choice between "tired of hearing" about the e-mails and "the media should continue to cover" the subject, most people chose the former. There might very well be people who are both tired of hearing about the topic and who believe it should still be covered by the media -- suggesting that the number of people who are sick of it is quite possibly more than 59 percent.
Interestingly, registered voters -- presumably people who've received more communication about the election -- are more likely to say they're sick of the topic. There's still a partisan split, with Republicans more likely to say that the press should keep reporting than Democrats. But independents have moved strongly toward Sanders's point of view. (Sanders, of course, is himself an independent.)
The Benghazi committee has been diligent about chasing down the e-mail story, certainly in part because it is a weakness of Clinton's. But between House Majority Leader Kevin McCarthy's apparent suggestion that the committee was targeting Clinton and people having reached their fill of the main point of leverage against Clinton, Thursday's hearing might not be the public relations success that Republicans would have hoped.
