Wisconsin governor Scott Walker added his voice to a growing chorus of conservative leaders calling on Congressman Paul Ryan to join the Republican presidential race. Walker, one of the country’s most popular figures with rank-and-file Republicans, says that Ryan’s leadership on the difficult issues is what the country needs now.

“Paul Ryan is one of the most courageous people I know,” Walker said. “Now, more than ever, we need a president with courage. We need leaders who care more about the next generation than they do about the next election. That’s Paul.”
