text: When running for president, the candidate has a group of electors. With each candidate habving their own group of electors, it provides without having to visit each state to nget their vote. The only thing the president is required to do is to wait. In reality, the preisdent doesn't even need to campaign, since the electors in the college votes are what matter. So, the candidate could just bribe the electors for certain states and he/she has that states' vote.
