5% undecided for GA, if they split 4-1 Trump, he wins 48-44 in the three-way. Even if they somehow split 3-2 Clinton, it's a 46-46 tie. The way it would work out for Clinton is if Johnson gets a notable amount of late deciders, if we split it 3-1-1 (Clinton-Trump-Johnson), then Clinton ekes it out 46-45.
As you can see, Trump is probably still the favorite on some level in this state.
Yes, I'd agree with this from my perception on the ground (which is admittedly limited to my social circle and the people I work with). I think Trump has slightly more support overall. Whether that support translates into more votes is a different and more interesting question. There seems to be more enthusiasm among the Clinton supporters. I think it really could go either way.
