Phrases using the word vote

[Entropy_Rising]

It's driving me nuts, I've been browsing through some online dictionaries and for the life of me I can't pin down the proper way to say "I voted for 'someone'" in Chinese.

I voted for Obama/McCain.

and

Who did you vote for?

are the sentences I'm basically trying to say.

Scouring the dictionaries, I have found

投某人一票 vote for someone?

投某人票 vote for someone?

投票赞成~ vote in favor of ~ (is this for policies only? i.e. vote in favor of gun control? Or can you use this with people?)

投票支持~ vote for/in favor of ~ (policies? people? both?)

投票反对～ to vote against something

投票表决 to put something to vote, to vote on x

So...

投奥巴马一票？

投麦凯恩票？

我投票支持了奥巴马？

我投票赞成了麦凯恩？

你投了谁票？

I really don't know. Thanks.

[ImBmen]

I voted for Obama/McCain.

我（把票）投给了奥巴马。

我投了奥巴马一票。

Who did you vote for?

你(把票)投给谁了?

你投谁了一票?

the words in bracket can be omitted.and the character '了'

is important,it's used in the past tense.shows you already voted.

[trevelyan]

Why not just say who you 支持 and avoid the more complex construction?

[Lu]

Because to support is one thing, and to actually cast your vote for that person another.

[xiaocai]

Totally agree with Lu.

And 投一票给ImBmen的答案.
