When people say they are undecided, I don't think it necessarily means that they don't know what the candidates' platforms are, or that they are waiting to hear anything new from the candidates. Sometimes, they know what the candidates are about but are waiting to decide inside themselves as to which values they prioritize and which things they can live without versus the ones they must have.
Get used to me. Black, confident, cocky; my name, not yours; my religion, not yours; my goals, my own; get used to me. -Muhammad Ali
