Ohio Republicans continue to disagree with President Bush when it comes to how much money should be spent on highways. G-O-P members of Congress say a more expensive version of the highway spending bill already passed by the Senate is better than Bush's bill, which allocates fewer dollars. Bush has said he will veto any bill bigger than 256 (b) billion dollars. Most in the Ohio delegation and Governor Taft prefer a bill that includes 275 (b) billion to 318 (b) billion. Senator George Voinovich says if the president doesn't like the more expensive bill he can veto it, and the Senate can override his veto. A Rutgers University specialist on Congress says it's not unusual for members to part company with the White House when it's on an issue important to their own political survival.
