5.+Is+the+ad+a+positive+or+negative

I believe that the advertisment has a negative slant towards Barak Obama. The ad makes John McCain look like he is a reformer and is willing to make positive changes to the United States immigration laws. However, Obama is being shown to be a non reformer, or as someone who is not interested in making America's immigration policies better. With negative ad campaigns, such as this, it stops people from forming a positive opinion about Barak Obama's leadership abilities.
