Michael Sam Is Not a âDistractionâ Dave Cullen February 11, 2014. A few minutes later, I understand why it all feels like a round of deja vu. The Upper West Side Celebrates An Imaginary Israelâs Birthday Vered Kellner April 14, 2013. Much of the rest of the debate provided a sense of deja vu. Romney Puts Perry on Defensive Howard Kurtz September 12, 2011. Which is great for me, I don't want to do deja vu all over again.
