[EX Q]: San Diego (CNN) -- I bet it sounded like a good idea at the time. Now, not so much. "It" was the ill-conceived decision by GOP presidential hopeful Rick Perry to hitch his wagon to the clownish Arizona Sheriff Joe Arpaio, an opportunist who in recent years has taken to rounding up illegal immigrants and parading them outside his jail to catch the attention of television cameras. How did Perry get mixed up with that circus? Simple. The Texas governor got into a political scrape, and made the mistake of overcompensating. He was looking for quick validation from his party's nativist fringe because he had gotten hammered by GOP rivals for signing, in 2001, a reasonable bill in the Lone Star State that allows illegal immigrants who go to college to pay what other residents pay: in-state tuition.Ruben Navarrette Jr.: Rick Perry has hitched his wagon to Arizona Sheriff Joe ArpaioPerry was foolishly looking for quick validation from his party's nativist fringe, Navarrette saysJustice Department has accused Arpaio of discrimination and racial profiling, he saysA once-promising candidate has lost his bearings, Navarrette says of Perry

[EX Q]: (CNN) The days following the September 11, 2001, attacks were marked by political solidarity over confronting America's enemies. No longer. As the 15th anniversary of the horrific attacks approaches Sunday, the political world is bitterly divided on how to address terrorism and national security. Donald Trump dominated the GOP primaries after breaking with key elements of his party's post-9/11 ethos. He blamed former President George W. Bush, whose original response to the attacks sent his approval ratings to historic highs, for the terrorist strike. And Trump has proposed banning Muslims from entering the United States. Though he's softened the proposal somewhat in gearing up for the general election, his stance still represents a dramatic departure from Bush's visit to the Islamic Center of Washington, DC, six days after the attacks to proclaim "Islam is peace."Americans remain committed to the fight against terrorismBut that unity fizzles once Washington gets involved 
 Questions:_'s decision to base his campaign around a vision of a nation under siege from foreign extremism may have contributed to the mood. (A) America (B) Donald Trump (C) GOP (D) George W. Bush (E) Muslims (F) United States (G) Bush (H) Islamic Center of Washington (I) DC (J) Islam (K) Americans (L) Washington
