"Vote goes for" vs "Vote goes to"
Solution 1:
I would think the first usage could be correct in sentences such as "my vote goes for nothing", meaning "my vote counts for nothing" (or possibly my vote is for sale for very little). "My vote goes to" would, I think, be more normal if you were planning to vote for somebody.
Solution 2:
'My vote goes to' is correct.
My vote goes to Barack Obama
'My vote goes for' is incorrect. You would say something like:
I'll be voting for Barack Obama
or
I vote we all go for dinner!
