Jim Geraghty of National Review and Rich McFadden of Radio America react to news of yet another terror attack in the UK which targeted British Muslims outside of a London mosque after their evening prayers for Ramadan. They also discuss the Supreme Court's announcement that they will take up the partisan gerrymandering case in the state of Wisconsin to determine whether or not the act is unconstitutional. And they respond to Erick Erickson's sensationalist comments as he refers to the left as "America's ISIS" and advocates for state secession.
