USC/LA Times national tracking poll (through 10/2) Trump +4.6%
Trump: 47.0% (+0.1)
Clinton: 42.4% (+0.2)
It's worth noting that the sample has six of the seven debate days in it now (with the seventh day being debate night). There really is no significant statistical change outside of basic noise with this survey. (Trump netted 1.1% over the week.)
Trump was at 46.2 before the debate (9/26) and is at 47 now. Clinton was at 42.7 before the debate and is at 42.4% now. This poll, at least, has the debate as a non-event, which is in step with the polling after most debates.
And is out of step with all other polling after this debate
