The House Republicans on Tuesday made it clear to anyone who had missed it that they are not interested in a deal on the current federal budget. In a meeting at the White House, they rejected a deal to get through the next six months. President Obama, silent for too long on this fight, emerged from the meeting to say that he would tolerate no more ideological gamesmanship. But the Republicans, if anything, only increased their demands, and a government shutdown seemed likely to begin on Friday.

That the Republicans are not interested simply in reducing the deficit was made clear when the House Budget Committee chairman, Paul Ryan, released his budget plan for 2012 on the same day as the talks to finish the 2011 budget were falling apart. It was less a budget-balancing effort than a press release for the 2012 elections. Similarly, the party’s refusal to accept Mr. Obama’s overly generous budget offer for this year makes clear that its leaders prefer a shutdown to abandoning their ideological crusade to abolish their least favorite government programs.

If their goal was to reduce spending, they would have accepted the Democrats’ offer to cut $33 billion out of the budget for the next six months — the same amount as Republican leaders had originally requested before Tea Party members forced them to double it earlier this year. As the president noted, that offer constitutes the largest cut to domestic discretionary spending in history.

But Speaker John Boehner and his negotiating team have continually moved the end zone. They spurned the specific cuts proposed by the Democrats because they did not end the programs reviled by the Republicans, including education improvements, health care reform and infrastructure rebuilding. They now want a total of $40 billion, a target that just emerged on Tuesday.
