I believe that we don't really have free will, we are just like "objects" with different atrributes and properties and we are rolling down an inclined slope that is the environment we live or in other words our life, we just react at any "objects" or information we percieve in our way downwards, our path is probably pretetermined before we even started rolling.

Our "atributes and properties" are defined by our genes, personality/ life experience so far and can change with time, even small factors like a tree at 100m from our home could play a role in who we are and change a bit our "attributes". A small obstacle in our way could leave as a "dent" and affect our remaining course.

randomness and chance might have more influence in us than "free will"

In other words we are like super complicated objects created from a class and we just react to the information that is pased to us.

If time travel was posible and we traveled back in time just before we vote for the OP would we change our mind and vote differently this time? my opinion is that if all other factors remained the same, we would not vote differently, if some factors changed/added or removed, like having a phone call this time or a dog barked at distance, this could posible make us react differently.
