Re: AD to get people to vote
Hi JoseMTorresPR and welcome to the forum.
It's hard to be sure without more details but I do think it's likely your purpose will be disallowed by Google's policies. Very generally speaking AdWords is intended to advertise products, services or information that add value to the Net and simply getting people to vote in a competition is likely to fall foul of one or more policies.
Can you provide us with some more details? A URL of your site would be ideal.
