In DC this weekend there was a festival to mark the end of cherry blossom season. It’s been an annual tradition since 1912, when the mayor of Tokyo gave the city 3,000 of the trees as a symbol of friendship. On Saturday, the crowds were out in force, lining a sunny Constitution Avenue to watch military units march behind twirling cheerleaders, past the soft pink blooms in Potomac Park.

In Washington, of course, political chatter doesn’t stop for a parade, and this week was no exception. On Saturday, all the talk was of who would replace Justice John Stevens on the Supreme Court. Appointed by Republican president Gerald Ford, Stevens’ departure at age 90 marks the end of a less-partisan era. His nomination, the last not to be televised, was approved in just 19 days. During the hearings, he was not even asked about his views on abortion.

In his 35 years on the bench, Stevens drifted left as his fellow justices strode right, becoming an increasingly distinctive liberal voice, and a powerful defender of abortion, gay rights, and limitations on the use of the death penalty. To his and Stevens’ credit, President Ford never regretted the nomination. In 2005, he wrote: “I am prepared to allow history’s judgment of my term in office to rest (if necessary, exclusively) on my nomination 30 years ago of John Paul Stevens to the US Supreme Court.”

With midterms fast approaching, the retirement is both a blessing and curse for Obama. Slate has a good summary of the choice he faces here, from the safe Merrick Garland to the bold Diane Wood. Ultimately, that will depend on how big a fight he wants to pick.

For us political Brits living stateside, it’s all a welcome distraction; there’s been a noticeable surge in procrastination recently, as jealous eyes trawl election blogs, wishing they were at home amidst the action.

On that topic, I was interested to see the Tories’ commitment, on page 75 of their manifesto, to introduce California-style referendums, triggered by petitions of 5 per cent of local people. Just occasionally, a golden ticket flutters out of the hot air at Tory HQ, and this is one such moment. If we believe in our arguments, progressives should welcome the chance for more direct democracy. The Tory pledge should prompt some self-reflection from Hazel Blears, whose time as minister for local government generated much talk about ‘empowerment’, but few substantive reforms.

Depending on how it’s introduced, the move could have a powerful effect. Here in the US, around half of all states have referendum provisions, and in California, voters have been able to petition questions onto the ballot since 1911. Over the last decade, around 60 referendums were put to the California people in this way. About a third were passed, making substantial changes to state law.

Of course, many of these referendums have been controversial, and many regressive – a cap on property tax, restrictions on illegal immigrants’ use of public services, and, more recently, Prop 8’s infamous assault on gay marriage. But not all have been. It’s worth looking at the list of past referendums here, which reveals a wider range of topics, and not just on lightning rod moral issues.

From California’s experience, we know the key lies in implementation: what is the scope of local referendums, and how will the process work? In recent years, the process has become increasingly professionalised. For a spare $1 million, paid circulators can be hired to all but guarantee the success of a petition; spending is up 1,200 per cent since 1974.

The impact of the Tory proposal, then, will depend in the details. To really hand power to the people, and not special interests, caps on spending will need to figure prominently in their plans.
