Bob Dole no longer recognizes the Republican Party that he helped lead for years. Speaking over the weekend on “Fox News Sunday,” he said his party should hang a “closed for repairs” sign on its doors until it comes up with a few positive ideas, because neither he nor Ronald Reagan would now feel comfortable in its membership. For Op-Ed, follow @nytopinion and to hear from the editorial page editor, Andrew Rosenthal, follow @andyrNYT.“It seems to be almost unreal that we can’t get together on a budget or legislation,” said Mr. Dole, the former Senate majority leader and presidential candidate. “I mean, we weren’t perfect by a long shot, but at least we got our work done.” The current Congress can’t even do that, thanks to a furiously oppositional Republican Party, and that’s what has left mainstream conservatives like Mr. Dole and Senator John McCain shaking their heads in disgust. The difference between the current crop of Tea Party lawmakers and Mr. Dole’s generation is not simply one of ideology. While the Tea Partiers are undoubtedly more extreme, Mr. Dole spent years pushing big tax cuts, railing at regulations and blocking international treaties. His party actively courted the religious right in the 1980s and relied on racial innuendo to win elections. But when the time came to actually govern, Republicans used to set aside their grandstanding, recognize that a two-party system requires compromise and make deals to keep the government working on the people’s behalf. The current generation refuses to do that. Its members want to dismantle government, using whatever crowbar happens to be handy, and they don’t particularly care what traditions of mutual respect get smashed at the same time. “I’m not all that interested in the way things have always been done around here,” Senator Marco Rubio of Florida told The Times last week. This corrosive mentality has been standard procedure in the House since 2011, but now it has seeped over to the Senate. Mr. Rubio is one of several senators who have blocked a basic function of government: a conference committee to work out budget differences between the House and Senate so that Congress can start passing appropriations bills. They say they are afraid the committee will agree to raise the debt ceiling without extorting the spending cuts they seek. One of them, Ted Cruz of Texas, admitted that he didn’t even trust House Republicans to practice blackmail properly. They have been backed by Mitch McConnell, the minority leader, who wants extremist credentials for his re-election. At long last, this is finally drawing the rancor of Mr. Dole’s heirs in the responsible wing of the party. Senator Bob Corker of Tennessee said that negotiating on a budget was an “issue of integrity.” Roy Blunt, Lamar Alexander and many others have encouraged talks, and Mr. McCain (who was not above veering to the far right when he was running for president in 2008) now says the Tea Partiers are “absolutely out of line” and setting a bad precedent. “We’re here to vote, not here to block things,” he said last week. “We’re here to articulate our positions on the issues and do what we can for the good of the country and the let the process move forward.” Already, the mulish behavior of Congressional Republicans has led to the creation of the sequester, blocked action on economic growth and climate change, prevented reasonable checks on gun purchases and threatens to blow up a hard-fought compromise on immigration. Mr. Dole’s words should remind his party that it is not only abandoning its past, but damaging the country’s future.
