Xavier: It's interesting that some folks (including, it seems, you) are blaming Mr. Clark's loss on his running a lackluster campaign. From all I saw and read, he campaigned quite hard. I saw about 10 to 1 more Clark signs and only Clark billboards. I think he also worked to present himself as a rightg-of-center candidate. There's also the possibility that Ms. Vinis, campaigning as a progressive who would follow the same general philosophy as Mayor Piercy, was simply more to the liking of the voters.
Yes
