It was mixing business and pleasure that got you in trouble I suspect. She was probably nice to you at first because she saw you simply as a canvasser doing your job, she didn't think the encounter actually meant anything beyond that. The fact that you wanted to be her friend and came to her house outside of this professional capacity probably freaked her out because she had not seen your relationship in this way. Just like when you go to a restaurant and may make small talk with a waiter/waitress, but you don't mean anything more by it, it's just pleasantries in a professional relationship. You don't expect to see that person again and you may be a little weirded out if they showed up by your car in the parking lot wanting to be friends on Facebook.
You may have felt like you had a connection, but she just saw you as someone doing a job that she should be polite to. Knocking more than once and going to the back door just made matters worse.
