Yes, you can.
I'm going1 to go2 to vote.
The two gos indicate different things:
So this sentence would be most appropriate if you're about to head out the door to go to your local voting site, and you want to tell someone the reason you're leaving.
Most verbs can be put together like the above (A to B to C to D). However, the verb of motion go is a special verb, and it can appear with another verb without to in-between:
I'm going1 to go2 vote.
This means the same thing as the above. This shorter sentence is more natural-sounding, particularly for American speakers; usually we leave out the to when we use go like this. (Some British English speakers regard this construction as an Americanism, and a few (particularly older) speakers don't accept it.)
I'm going1 to vote.
The simpler sentence "I'm going to vote" is different. It only has the future going to, not the verb of movement go. So it means "I will vote" (at some point in the future) and doesn't tell us that you're about to go somewhere to vote. This simpler sentence would be appropriate if you've decided in advance that you will vote. It can be said weeks or months in advance.
