GOP today is plain scary

The political press – and presumably the donors and activists who consume it – has handed Jeb Bush his walking papers. Another poor-to-middling debate performance Wednesday night in Colorado is the proximate cause.

The debate left me unusually queasy, and I find the notion of Bush’s departure from the field even more unnerving. I consider Bush pretty smart, pretty honest and pretty competent. You won’t get me to defend his boneheaded and fully anticipated attack on Marco Rubio’s Senate absenteeism, however. I have limits.

Bush’s most telling exchange of the night was not, however, with Rubio. It was with moderator John Harwood: “Gov. Bush, in a debate like this four years ago, every Republican running for president pledged to oppose a budget deal containing any tax increase even if it had spending cuts 10 times as large.”

That 2011 pledge was prime evidence that the Republican Party had departed the realm of politics for religion, where doctrinal devotion trumps the crass realities of the material world. Bush, who wasn’t a candidate at the time, had suggested that he would embrace such a preposterously bountiful political windfall in a hurry.

During the debate, however, when Harwood probed to see if Bush was still on solid ground, Bush demurred. He was unwilling to admit subscribing to a belief system – political compromise within a system specifically designed for it – that much of his party considers disqualifying. And let’s be clear: The hypothetical is getting 10 times what you give up to your domestic political opponent. That’s a good deal.

The devolution of one of the nation’s two major political parties, and its sanction of nonsensical beliefs on taxes, science and other issues, is the most important political development of our era. Bush’s candidacy originated as a conscious backlash to that.

Before his campaign even began, he said a Republican would have to risk losing the primary to win the general. Bush was saying that his party had become so extreme that the policy positions required to please its base were toxic to a general electorate. He would have to risk the base’s ire to have a shot.

Bush’s burdens didn’t stop there, of course. He is a quintessentially establishment figure at a moment when anti- establishment rage fuels his party. He is burdened by the presidency of his brother, whose fiscal failure and foreign disasters have made virtually identical conservative policies much more difficult to defend. And he has proved to be a sometimes awkward campaigner, seemingly out of sync with changing times.

Indeed, on the Republican stage, Bush appears as Dylan’s Mr. Jones, an earnest square surrounded by tie-dyed merry pranksters. Yet it’s not his beliefs that distinguish him from the crowd. He is socially conservative to a fault. And like his competitors, Bush proposes tax cuts that favor the wealthy and would produce trillions in additional debt even as he decries current debt levels.

Surveying the debate rhetoric, budget analyst Stan Collender saw Bush as one of the guys: “The candidates talked about trillion-dollar tax cuts that somehow wouldn’t increase the deficit and about spending that should be reduced without saying what they would cut. They disagreed with nonpartisan analyses that showed their tax plans losing trillions even when those scores were produced using the GOP-preferred dynamic scoring techniques. They supported plans that will increase the U.S. debt but complained bitterly about raising the federal debt ceiling to accommodate those plans.”

A Bush presidency would almost certainly produce huge deficits and greater inequality, just as his brother’s did. He is sworn to uphold the party doctrine of magic tax cuts. But like John Kasich, who has even less chance of winning the nomination, Bush is a bridge to a time when the Republican Party wasn’t a danger to itself and others.

When Bush declined to support trading $10 in spending cuts for $1 in tax increases, he was essentially saying the bridge had collapsed. Try as he might, he can’t span the chasm between the real world and the Republican world. And if Bush can’t, who can?
