So, Republican Senator Marco Rubio, how old IS the earth?

He's not a scientist, but he does know how to tell them when they're wrong.

GQ interviewed Marco Rubio, the junior Republican senator from Florida, former "crown prince of the Tea Party movement", and runner-up in the race to be Mitt Romney's vice-presidential candidate.

Marco Rubio does not have a firm grasp on reality.

GQ: How old do you think the Earth is? 

Marco Rubio: I'm not a scientist, man. I can tell you what recorded history says, I can tell you what the Bible says, but I think that's a dispute amongst theologians and I think it has nothing to do with the gross domestic product or economic growth of the United States. I think the age of the universe has zero to do with how our economy is going to grow. I'm not a scientist. I don't think I'm qualified to answer a question like that. At the end of the day, I think there are multiple theories out there on how the universe was created and I think this is a country where people should have the opportunity to teach them all. I think parents should be able to teach their kids what their faith says, what science says. Whether the Earth was created in 7 days, or 7 actual eras, I'm not sure we'll ever be able to answer that. It's one of the great mysteries.

What does François Bayrou's endorsement of Emmanuel Macron mean for the French presidential race?

The support of the perennial candidate for President will boost Macron's morale but won't transform his electoral standing. 

François Bayrou, the leader of the centrist Democratic Movement and a candidate for the French presidency in 2007 and 2012, has endorsed Emmanuel Macron’s bid for the presidency.

What does it mean for the presidential race?  Under the rules of the French electoral system, if no candidate secures more than half the vote in the first round, the top two go through to a run-off.

Since 2013, Marine Le Pen has consistently led in the first round before going down to defeat in the second, regardless of the identity of her opponents, according to the polls.

However, national crises – such as terror attacks or the recent riots following the brutal arrest of a 22-year-old black man, who was sodomised with a police baton – do result in a boost for Le Pen’s standing, as does the ongoing “Penelopegate” scandal about the finances of the centre-right candidate, François Fillon.

Macron performs the most strongly of any candidate in the second round but struggles to make it into the top two in the first. Having eked out a clear lead in second place ahead of Fillon in the wake of Penelopegate, Macron’s lead has fallen back in recent polls after he said that France’s rule in Algeria was a “crime against humanity”.

Although polls show that the lion’s share of Bayrou’s supporters flow to Macron without his presence in the race, with the rest going to Fillon and Le Pen, Macron’s standing has remained unchanged regardless of whether or not Bayrou is in the race or not. So as far as the electoral battlefield is concerned, Bayrou’s decision is not a gamechanger.

But the institutional support of the Democratic Movement will add to the ability of Macron’s new party, En Marche, to get its voters to the polls on election day, though the Democratic Movement has never won a vast number of deputies or regional elections. It will further add to the good news for Macron following a successful visit to London this week, and, his supporters will hope, will transform the mood music around his campaign.

But hopes that a similar pact between Benoît Hamon, the Socialist Party candidate, and Jean-Luc Jean-Luc Mélenchon, the Left Front’s candidate, look increasingly slim, after Mélenchon said that joining up with the Socialists would be like “hanging himself to a hearse”.
