Great crises often produce great leaders. Unfortunately, sometimes the timing isn’t right, and neither is the leader.

Barack Obama came into office in the midst of a great economic crisis. Although hopes were high, he did not rise to the occasion. Now that the clouds of enthusiasm and excitement have parted, we see he was obviously unsuited for the task at hand.

President Obama has failed to meet America’s economic challenges.

His three years of spending, regulating, and taxing have not restarted the economy. Unemployment remains at a shocking 9.1 percent. Economic growth is hovering on the edge of a renewed recession.

Abroad, the standing of the United States appears uncertain and adrift under the failed leadership of a president who prefers chastising allies to condemning foes.

Fortunately, America may get a second chance: Mitt Romney is running for president, and I am proud to endorse him.

Alone among the contenders, he possesses the unique qualifications to confront and master our severe economic predicament. His abiding faith in our country’s exceptional historical position as a beacon of freedom will make him the most important leader in a world that depends upon a strong America to stay at peace.

As governor of Massachusetts, he turned that state’s budget around from deficit to surplus while simultaneously cutting taxes, but that is not the full measure of what he will bring to the presidency. His time in government was a moment of service — a way to give back to our country — following a distinguished career in the private sector, where he launched companies and turned around troubled ones.

When the 2002 Winter Olympics were on the verge of collapse thanks to a bid-rigging scandal, Romney was asked to take over. The attacks of September 11 created a security nightmare. Romney presided over a highly complex security mobilization, addressed the management troubles plaguing the games, and staged one of the most memorable competitions ever seen on American soil.

Romney is running for president because he is deeply committed to our country, and troubled by its current condition. I believe he can turn it around.

He’s formulated an economic plan — a set of alternatives to the government-oriented programs that Barack Obama has put in place — that is unparalleled in the history of American electoral campaigns. By pressing for fundamental change in the way that Washington taxes and spends, issues regulations, uses energy, interacts with our major trading partners, and deals with our labor force, he fully envisions a way to place America back on the path toward rapid economic growth and full employment.

And at his core, Mitt Romney is a man of great character. He and his wife, Ann, have been married for more than four decades. She is the love of his life. Together, they have five sons and 16 grandchildren.

But he’s not only a family man, he is a man of principle. He believes in the bedrock conservative ideals of limited government and free enterprise. He will stand up for America’s allies when they are threatened, with fortitude. And he will face down our adversaries. He is a formidable person, and he will certainly be a formidable president. Our allies can count on it, and our enemies should expect it.

Crises indeed produces great leaders. Sometimes it just takes awhile.
