Jim Messina, campaign manager for President Barack Obama

"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."

Republican National Committee Chairman Reince Priebus

"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."

Former President George W. Bush

"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."

Democratic National Committee Chairwoman Debbie Wasserman Schultz

"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."

Senate Majority Leader Harry Reid, D-Nev.

"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."

Ohio Sen. Rob Portman

"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."

Senator Portman was one of several prominent Republicans under consideration by Romney as his running mate

Tim Pawlenty

"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."

Tim Pawlenty is the former governor of Minnesota and was also under consideration by Romney to be his vice presidential nominee.

Sen. Marco Rubio, R-Fla.

"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."

Nancy Pelosi

"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."

New Jersey Gov. Chris Christie

“With Paul Ryan on the ticket this is a team that understands the economic stagnation our country has been facing the last four years and the urgency with which we need to change course. The Romney-Ryan team is uniquely positioned to make the tough choices necessary to confront our fiscal challenges and get results.”

U.S. Rep. Scott Garrett, R-N.J., vice chairman of the House Budget Committee

“I’ve seen firsthand how Chairman Ryan has brought Republicans and Democrats together by articulating common-sense solutions. I look forward to helping my friend, Paul Ryan, continue his strong record of leadership once he is elected vice president of the United States.”

Senator John McCain

"Paul Ryan brings the balance of understanding how the Congress works, understanding how the budget process works and understanding the entire process and established relationships that I think will make him most effective in getting the Mitt Romney agenda through the Congress.

Former Sen. Rick Santorum R-Pa.

"Congressman Paul Ryan is an outstanding choice as our country’s next vice president, and today’s announcement demonstrates Governor Romney’s commitment to returning fiscal sanity back to Washington, D.C. I have long supported Paul Ryan’s fiscal and entitlement reforms to return our country back on a path of fiscal health. At a time when our country is at an economic crossroads, Congressman Ryan’s depth of knowledge on how to tackle these challenges is unparalleled. He will serve Governor Romney and our country well to undo the flawed policies of the last four years. In addition to Congressman Ryan’s stellar fiscal conservative positions, he is indeed a full-spectrum conservative. He is solidly pro-life, pro-family, and will be an advocate for our military and our national security priorities. I look forward to supporting the Romney-Ryan ticket in the weeks to come."

Former Alaska Gov. Sarah Palin

We must now look to this new team, the Romney/Ryan ticket, to provide an alternate vision of an America that is fiscally responsible, strong, and prosperous – an America that understands and is proud of her exceptional place in the world and will respect those who fight to secure that exceptionalism, which includes keeping our promises to our veterans.

Former Vice President Dick Cheney

"I think that what he [Romney] has done here is take, and put front and center in his campaign, somebody who has been spending time and energy addressing the most serious problem we face as a nation.”

Gov. Rick Perry, R-Tx.

"The choice of conservative budget hawk Paul Ryan underscores Mitt Romney’s commitment to downsizing Washington, fixing our economy and restoring American job creation.

Paul Ryan will energize economic voters, young voters and blue collar voters who know President Obama is destroying American jobs and hope for the future. This is an exciting choice that underscores the Republican Party’s commitment to American job creation and fiscal responsibility."
