U.S., Britain tend to follow similar paths

In recent times, British and American politics often have flowed in parallel currents.

Margaret Thatcher’s election as prime minister in 1979 was followed by Ronald Reagan’s election as president in 1980. As Charles Moore notes in his biography of Thatcher, the two worked together, albeit with some friction, reversing the tide of statism at home and ending the Soviet empire abroad.

They seemed to establish British Conservatives and American Republicans as their nation’s natural ruling parties.

In time, Democrats and Labor responded. Bill Clinton’s “New Democrat” politics prevailed in 1992, and Tony Blair’s New Laborites, adapting Clinton’s strategy, won the first of three big national landslides in 1997.

But after any party is in power for an extended period, its wingers start to get restive — rightwing Republicans and Conservatives, left-wing Democrats and Laborites.

They complain that their leaders failed to enact needed changes and betrayed core beliefs. They take their party’s past electoral success for granted and push for a return to ideological purity.

An internal rebellion in the Conservative party overthrew Thatcher in December 1990, and the hatreds it inspired festered for years.

Thatcher’s successor, John Major, did win another term in May 1992. But he was hectored by Thatcherite true believers more obdurate than Thatcher had been in office. This intraparty civil war raged through three electoral defeats and subsided only after David Cameron was elected party leader in 2005.

In America, anti-tax conservatives rebelled at George H.W. Bush’s acceptance of tax increases in 1990, and Reagan speechwriter Pat Buchanan launched a quixotic challenge of Bush in the 1992 primaries.

That, plus Ross Perot’s independent candidacy, led to Bush’s loss to Clinton that November. Right-wing frustration promptly found targets in the Clinton tax increases and Hillary Clinton’s health-care plan, and Newt Gingrich’s Republicans captured the House in 1994.

Then Bill Clinton’s successful negotiations with Gingrich caused discontent on the Democratic left. It supported Clinton on impeachment but gave 2.9 million votes to Ralph Nader in 2000, which helped defeat Al Gore.

George W. Bush’s bipartisan achievements on education and Medicare and continued spending increases caused distress on the Republican right. It found a voice after he left office in the tea party movement, whose anger was directed at “establishment” Republicans as well as at President Barack Obama.

Blair’s victories came with diminishing percentages and turnout. On the left, there was increasing rage at Blair’s support of the Iraq war, and today Blair is virtually a non-person, unmentioned if not reviled, in the party he led. No one follows his example.

After Labor’s defeat in 2010, the party rejected as leader the Blairite David Milliband in favor of his brother Ed Milliband, who more faithfully represented the views of their Marxist intellectual father.

Milliband — “Red Ed” to the Conservative press — has led his party sharply to the left, backing higher taxes on high earners, a mansion tax on big properties and a freeze on energy prices. He’s even considering renationalizing the railroads, though privatization has been widely accepted.

At the behest of the teacher unions, Labor opposes Education Minister Michael Gove’s “free schools” (similar to American charter schools), despite their success with disadvantaged students. The latest Labor TV ad depicts Conservatives as snobbish “toffs” — old-fashioned class warfare.

Milliband’s critics say his strategy is to nail down 35 percent of the vote — quite possibly enough to win in a nation with competitive minor parties and parliamentary district boundaries that heavily handicap Conservatives.

An obvious question: Why is Milliband’s Labor party abandoning a governing strategy so successful under Tony Blair? Another question: Why would American Democrats such as New York Mayor Bill de Blasio and Sen. Elizabeth Warren abandon a strategy so successful under Bill Clinton?

One answer is that they’re acting out of genuine conviction. Another is that circumstances have changed.

Blair and Clinton adapted after their party suffered multiple serious defeats. Today’s Labor and Democratic leftists act out of frustration with how their parties have governed.

Party politics tends to attract people of strong beliefs, left and right. Until they get whacked repeatedly by defeat, they’ll try to advance them as far as they think they can.
