"Mitt Romney is a leader with the skills, the background and the character that our country needs at a crucial time in its history. Following four years of failed leadership, the hopes of our country, which have inspired the world, are growing dim, and they need someone to revive them. Governor Romney is the man for this moment, and he and I share one commitment: We will restore the dreams and greatness of this country."
_Rep. Paul Ryan, R-Wis., chosen Saturday as likely Republican presidential nominee Mitt Romney's running mate
"Paul is a man of tremendous character. Paul Ryan works in Washington, but his roots remain firmly planted in Janesville, Wis. His integrity is unquestioned, his word is good. In a city that's far too often characterized by pettiness and personal attacks, Paul Ryan is a shining exception. He doesn't demonize his opponents. He understands that honorable people can have honest differences. He appeals to the better angels of our nature. There are a lot of people in the other party who might disagree with Paul Ryan; I don't know of anyone who doesn't respect his character and judgment."
_Likely Republican presidential candidate Mitt Romney
"In naming Congressman Paul Ryan, Mitt Romney has chosen a leader of the House Republicans who shares his commitment to the flawed theory that new budget-busting tax cuts for the wealthy, while placing greater burdens on the middle class and seniors, will somehow deliver a stronger economy. As a member of Congress, Ryan rubber-stamped the reckless Bush economic policies that exploded our deficit and crashed our economy. Now the Romney-Ryan ticket would take us back by repeating the same, catastrophic mistakes."
_Jim Messina, campaign manager for President Barack Obama
"My friend and fellow Wisconsinite Paul Ryan will serve America admirably as the next vice president of the United States. Governor Romney and Congressman Ryan have the knowledge, expertise and vision we need to get America working again and get our fiscal house in order. This is a great day for Wisconsin and for America."
_Republican National Committee Chairman Reince Priebus
"This is a strong pick. Governor Romney is serious about confronting the long-term challenges facing America, and Paul Ryan will help him solve the difficult issues that must be addressed for future generations."
_Former President George W. Bush
"Congressman Ryan has been called a serious person, but he, like Mitt Romney has seriously flawed ideas for our economy that have only failed us in the past. Congressman Ryan laid the groundwork in Congress for Mitt Romney's budget-busting scheme that gives an additional $250,000 tax cut for millionaires while punishing middle-class families with tax hikes of up to $2,000 a year. A Romney-Ryan ticket is sure to take us back and repeat the same catastrophic mistakes that got us into the mess we found ourselves in in the first place."
_Democratic National Committee Chairwoman Debbie Wasserman Schultz
"By picking Representative Paul Ryan, Governor Romney has doubled down on his commitment to gut Social Security and end Medicare as we know it. Romney's choice demonstrates that catering to the tea party and the far-right is more important to him that standing up for the middle class."
_Senate Majority Leader Harry Reid, D-Nev.
"Mitt Romney has made a great choice in Paul Ryan. He is an accomplished public servant and a leading voice on the most pressing issues facing our country. Paul is one of my best friends in Congress and someone I have worked closely with. I look forward to working closely with a Romney-Ryan administration to restore fiscal sanity and enact pro-growth policies to create jobs."
_Ohio Sen. Rob Portman, one of several prominent Republicans under consideration by Romney as his running mate
"Congressman Ryan is a respected leader and a bold thinker regarding the changes needed to restore America. His selection will also help Governor Romney win the key swing state of Wisconsin. I am excited about a Romney-Ryan ticket and look forward to doing all I can to help them win this election."
_Former Minnesota Gov. Tim Pawlenty, also under consideration by Romney to be his vice presidential nominee
""Throughout his life, Mitt Romney has made great decisions, and choosing Paul Ryan as his running mate is a truly inspired choice ... Paul Ryan is a courageous reformer who understands our nation's challenges, has proposed bold policy solutions to solve them, and has shown the courage to stand up to President Obama and other Washington politicians trying to tear him down."
_Sen. Marco Rubio, R-Fla.
"There is no question that former Governor Romney now owns the Republican, Ryan budget that puts millionaires ahead of Medicare and the middle class. Congressman Paul Ryan led House Republicans in voting to end the Medicare guarantee, which increases costs on seniors and weakens America's great middle class in order to give tax breaks to millionaires, Big Oil and corporations that ship jobs overseas."
_ Democratic Leader Nancy Pelosi of California
