question: What is the last name of the person who was said to have been elected because of the Immigration Act of 1965?
context: A Boston Globe article attributed Barack Obama's win in the 2008 U.S. Presidential election to a marked reduction over the preceding decades in the percentage of whites in the American electorate, attributing this demographic change to the Immigration Act of 1965. The article quoted Simon Rosenberg, president and founder of the New Democrat Network, as having said that the Act is "the most important piece of legislation that no one's ever heard of," and that it "set America on a very different demographic course than the previous 300 years."Immigrants differ on their political views; however, the Democratic Party is considered to be in a far stronger position among immigrants overall. Research shows that religious affiliation can also significantly impact both their social values and voting patterns of immigrants, as well as the broader American population. Hispanic evangelicals, for example, are more strongly conservative than non-Hispanic evangelicals. This trend is often similar for Hispanics or others strongly identifying with the Catholic Church, a religion that strongly opposes abortion and gay marriage.
