The ostensible reason for her visit on Tuesday was a premiere of a documentary about her years as Alaska governor, not an overtly political appearance.
But the timing — one day after Representative Michele Bachmann of Minnesota announced her candidacy for the Republican presidential nomination in Iowa — raised questions about how much ground Ms. Palin might be losing to rivals who are already lining up donors and building staffs in early-voting states.
Arriving here late Tuesday afternoon with her husband, Todd, Ms. Palin said she was still making up her mind.
“A lot goes into such a life-changing, relatively earth-shattering type of decision,” she said as she entered the Pella Opera House for the 5 p.m. screening of the film, to be followed by a cookout for 1,000. “Still thinking about it.”
Republican leaders in Iowa, which holds the nation’s first nominating contest early next year, acknowledged that Ms. Palin’s celebrity bought her a lot of time — maybe even until Labor Day — but said that remaining above the fray for too long had risks.

Experts say that eliminating the Parliament’s monthly commute could save $285 million each year. “We have a traveling circus that costs a lot and produces huge amounts of carbon dioxide,” said Ashley Fox, a British Conservative and member of the European Parliament who is campaigning to stop the practice. “We cannot keep this up.”

The Strasbourg shuffle is a prime example of the expensive diplomatic contortions that were necessary to appease Europe’s many constituencies — and seemed more affordable when times were flush. Much of the 27-nation bloc’s $182 billion budget for this year is doled out as agricultural aid or subsidies to poorer regions, and member states have wide discretion over how they use that aid. Right-leaning politicians from Finland to Italy have made the bloc’s spendthrift ways a populist campaign issue.

Last year, Italy was told to repay $1 million in European Union funds spent on holding an Elton John concert in Naples. This month, Britain’s prime minister, David Cameron, complained that leaders of the bloc had decided to spend $344 million on a new administrative building for themselves in Brussels, and urged them to reconsider.

“You do wonder whether these institutions actually get what every country, what every member of the public is having to go through as we cut budgets and try to make our finances add up,” Mr. Cameron told reporters.
