Poll as a born again Christian do you still sin

[HIM]

I think you are making to much of an assumption about "all" baptized believers.
Lots of sincere baptized believers are not taught about the power to not sin available to them and they may even be taught they will go on sinning because they are still in the flesh.
We are taught about forgiveness, repenting, confessing, and what sin is, but not about the Holy Spirit indwelling and what all He can do.

That is a fact and the number one failing of the Church today.
