A sampling of reaction from Republican leaders around the country:
Gov. Arnold Schwarzenegger of California, who followed Reagan's career path from movies to politics and keeps a bust of his "hero" in his statehouse office, noted "the tremendous force" Reagan was as a two-term governor of the Golden State before pursuing the White House.
"He served with dignity and determination, and left us with a blueprint for executive leadership that is still a model today," Schwarzenegger said. "Gov. Reagan promoted bipartisan cooperation, furthered economic growth and embraced government's duty to protect our natural resources."
House Majority Leader Tom DeLay, R-Texas, said Reagan's greatness was "an extension of his goodness," and he credited him with having "led America out of weakness and malaise to heights of strength and prosperity never before witnessed by any nation in history."
"The Gipper may be gone, but his legacy and influence on our nation will live on forever," Sen. Kay Bailey Hutchison, R-Texas, said. "Today we lost the father of the modern conservative movement."
Republican National Committee Chairman Ed Gillespie said Reagan was a president "of great historic impact who led the United States with strength and conviction." And "more than two decades after he was first elected president, the Republican Party still bears his imprint," he added.
Former House Speaker Newt Gingrich of Georgia said: "President Ronald Reagan proved that an American, raised in difficult family circumstance, in a small town, with no personal money, could not only could succeed but could rise to lead the cause of freedom and declare victory over the tyranny of the former Soviet Union."
