I am part of that 29% 
Arsenal voters are the majority in the Premier League voting you participated in but the minority in the forum. So is this Arsenal's season?
However, only 16% of voters chose City which surprised me, their performance so far has been quite impressive, scoring 17 goals in 7 games but it seems their defense is still not optimal, as well as Arsenal's, only Liverpool among the top three has a good defense.
It's actually 66% for Manchester City and not 16% for them. I think at this rate, Manchester City has monopolized Premier League that it's too obvious they are the one that are going to win this season trophy, I don't care if their defense is weak, other teams afe weak as well but one thing I love about their forward is that they don't joke with goals.
If Arsenal are going to be the favorite of this season, by now they would have be at the top of the table waiting to win the next game instead of Liverpool but they are right under Manchester City and nothing will change it until everyone is back from the international break.
Please read carefully, and check my quote above...
This is just a voting, there is no guarantee that the voting winner will win the title at the end of the season, this is just for fun, so relax... don't take it too seriously.

Check the table, the gap points between Liverpool, City, and Arsenal are very tight, which indicates that the three teams still have an equal chance of winning the title. IMO
