Roughly half of survey respondents with a cell phone say it's a smart phone. About half of those smart phone owners used their device to access social network info about a candidate or campaign. Thirty-five percent used their smart phone to fact-check campaign claims. Eighteen percent used it to post political commentary to a social network.
What does the "fact-check" mean?
Does it mean "to check the fact whether....?"
Thanks a lot
They use it to check that the claims made in election camaigns are factually correct.
