Writing in the Wall Street Journal, John Fund tackles President Bush's handling of immigration in his political column. Fund notes that Rush Limbaugh criticized Bush twice on Friday for his guestworker plan, saying, "We cannot maintain our sovereignty without securing and protecting our borders in an era where terrorists around the world seek entry to this country." According to Fund, [Bush] will have to engage critics in his own party more fully--especially since many Democrats will likely vote against his plan just to spite him. Many Republicans are steaming about what they see as White House obtuseness on immigration. . . . Even though the political impact of anti-immigration sentiment can be exaggerated, Mr. Bush would be wise to take steps to ensure that immigration doesn't become what crime and abortion became for the Democrats: wedge issues that drove many voters to the other party. He will not come close to passing a guest-worker program until he proves his bona fides in areas of legitimate concern on immigration."
