There appears to be a consensus view that Ms Marine Le Pen, candidate of the far-right National Front in France, will advance to a second-round run-off before losing by a wide margin to a more mainstream opponent. That's what happened to her father in 2002.
Not so fast. Ms Le Pen has a real chance to become France's next president. If she does, she might do much more damage to France's economy and its role in Europe even than she intends.
Her odds of winning are higher than most think. First, Ms Le Pen is part of a deeply flawed field of candidates. Mr Benoit Hamon and Mr Jean-Luc Melenchon have divided voters on the left. Mr Francois Fillon, candidate of the centre-right Les Republicains, has been badly damaged by corruption charges. Centrist candidate Emmanuel Macron has not yet been tested, and he has no reliable support base. Ms Le Pen might not have majority support, but her voters seem much more motivated than those of any of her rivals.
Last November, Mr Donald Trump won support from just 26 per cent of eligible US voters. Given lukewarm support for Mrs Hillary Clinton and the decision by millions of Americans to stay home, Mr Trump's passionate 26 per cent proved just enough for victory.
In addition, as with Mr Trump and those who fought for Brexit, Ms Le Pen has already shown great skill at speaking directly to the anxieties of millions of voters on questions of jobs, economic stagnation, immigration and security. On all these issues, headlines between now and election day are more likely to boost Ms Le Pen than any of her opponents, particularly if another terrorist attack takes place in the heart of Europe or if there is more violence between the French police and angry young people living in the banlieues on the outskirts of French cities.
Further boosting her chances, Mr Macron - her likeliest second-round opponent - may see support erode among centre-right voters as Ms Le Pen uses his role in the deeply unpopular Francois Hollande government against him. He is vulnerable in other areas as well. Mr Macron has yet to face the sort of scandals that have plagued Mr Fillon, and the scrutiny that comes with them, but that might change.
Just as Mrs Clinton faced embarrassing leaks of uncertain origin, so Mr Macron might still face similar challenges. It's also possible that support for his candidacy will decline sooner, and that the deeply flawed Mr Fillon will advance to the second round. In that case, it might well be voters on the left who decide to stay home.
If Ms Le Pen pulls off the upset, the damage she inflicts on France's economy and its place in Europe might not come through political means. She can't hold a referendum on France's European Union or euro membership, because Article 11 of France's Constitution allows for referenda on only questions that do not require constitutional change. Article 88 enshrines France's place in the EU. Nor will her party elect nearly enough members in June's legislative elections to form a National Front government. Forced to form a government with another party, probably from the centre right, Ms Le Pen will have almost no leverage on domestic policy - particularly on any move to alter the Constitution to leave the EU or euro zone.
Yet, if she wins, the uncertainty and unrest that follow her election might well send shockwaves through financial markets.
If global reserve managers, who probably hold €700 billion (S$1 trillion) of French government debt, decide to sell on a large scale, they might overwhelm the ability of European Central Bank quantitative easing to offset the move, triggering a sharp spike in French government bond yields. In that event, it's unclear where relief might come from. Or ratings agencies might decide that any attempt to redenominate French debt, as Ms Le Pen has promised to do, would constitute default, with a crisis of confidence in France's four "global systemically important banks" setting off a run on all French banks. In that scenario, we might also see capital flight as French depositors and investors try to move assets outside the country.
We can't predict how President Le Pen would respond to these pressures. She might not know either. But an emergency that forces an uncoordinated exit from the euro would create chaos - for France, for Europe, and beyond.
