Proposition 102 and Commercial Lies

This "Vote No Again" ad campaign is completely misleading. The proposition voted on in 2006 did include a definition of marriage, but also included several "extras" intended to stem funding for unmarried couples. The voters defeated that proposition because of the extra baggage. They did not defeat the proposition because of the definition of marriage.

Why does the main message of those who oppose this proposition have to mislead the public to try to get their message across? Is it because they have no other mainline message? Or maybe it's because they know that if the people got accurate information about Prop 102 the clear majority would support it? Whatever the reason, it's too bad their main point message is a lie.
