President Obama's administration is set to be rocked by scandal - at least, according to one political scientist's mathematical formula.

奥巴马政府即将爆发丑闻，至少一位政治学者的数学公式是这么推断的。

A newly-released report by scholar Brendan Nyhan predicts the reputation of the 44th US president will soon be marred¹ by controversy².

Where Are the Obama Scandals? calls the odds³ of scandal 'high and rising' after two years in office, based on his interpretation⁴（翻译，解释） of data from presidential scandals between 1977 and 2008.

Nyhan, a scholar at the University of Michigan, released the report to website Center for Politics on Thursday.

Serving as a guest columnist⁵, he presented detailed⁶ graphs illustrating⁷ the likelihood of a scandal to unfold before the 2012 presidential election - rising between 95 and 100 per cent by June of next year.

The report reads: 'Obama has been extremely fortunate: My research on presidential scandals shows that few presidents avoid scandal for as long as he has.'

He tested his hypotheses on scandal coverage⁸ data from Washington Post news reports and chronologies（年代） of presidential events covered by the New York Times.

'In the 1977-2008 period,' he wrote, 'the longest that a president has gone without having a scandal featured in a front-page Washington Post article is 34 months - the period between when President Bush took office in January 2001 and the Valerie Plame scandal in October 2003.'

Nyhan claims his research is supported by the lack of support among Republicans for the Obama administration, and predicts he will follow 'a similar trajectory⁹（轨道） to Ronald Reagan and Bill Clinton (who both suffered significant first-term scandals).'
