It's not tightening really, you have to cherrypick polls to reach that conclusion. He does seem to have moved back some of the Republicans to his side after hitting new lows of in-party favorability after pussygate, but Clinton has also slightly increased her numbers at the same time. The two effects have mostly canceled each other out and the small blips have been little more than statistical noise.
