When it comes to local elections, the important thing is that the person you vote for is in that job to represent you. Personally I wouldn't worry about the party they represent (unless it seriously clashes with your beliefs), and focus on who you think will do the best job of looking after your local area.
Case in point: During a local election years ago, I voted for the green party. Personally I wouldn't want them to win a national election, but at the time there were plans to build a huge gravel extraction and landfill side right on the outskirts of our village, and I knew the green party candidate wouldn't stand for it.
I didn't say nothing, I said very little. Of course politics do happen at the local level, but if you have no particular alignment, vote for whoever you think will represent your values best.
