Quick '08 Update

- A few ads were released this week: Hillary Clinton went on air with "Invisible", Barack Obama has a Spanish-language radio ad airing in Nevada, and Rudy Giuliani went on radio in South Carolina with "Fence" and "Out of Control".

(As background, PrezVid has a nice YouTube history of Giuliani's stance on immigration.) New York City Mayor Michael Bloomberg also added his opinion.
