Who's in? Who's out? Who's up? Who's down? What are the odds? Will he go first? Will she go first? While illegal in most other fields, politics is one of the few ways you can legally make a bet with insider knowledge.
Now I am as guilty as the next person for being an avid fan and user of the wise words and odds provided by Mike Smithson at PoliticalBetting.com, in part because his analysis is rarely wrong.
Some journalists use odds as a way of backing up a story now. If it is 2/1 that Ed Miliband will no longer be leader by the next election it is sometimes written with the same authority as an opinion poll. But anyone can sway odds if they work hard enough at it, or have enough money to throw at it. If Guido Fawkes announces that he is putting a pony on Chris Huhne to be out of the Cabinet by the end of May (a bet he clearly lost) it suggests he is attaching some credence to his claims. People are more likely to believe him.
In the days when no-one paid any attention to the Liberal Democrats, the potential to make money on bets was significant, I know of a rather lovely patio that was built courtesy of the proceeds of a by-election bet. Charles Kennedy placed a bet once on some glorious odds for the European Parliament Elections in 1994 because no-one believed the Liberal Democrats would get any seats at all. The main betting companies are much smarter now and work on their Liberal Democrat intelligence.
But something has changed which drives a stake through the heart of political betting - and it is driven by those at the centre of government.
From Caroline Spellman on forests, Kenneth Clarke on rape sentencing to Andrew Lansley on NHS reforms, politicians are no longer instantly losing their jobs. Instead they remain there to put things right. Even Vince Cable remained in post after the sting by the Telegraph (for which they were recently wrapped over the knuckles with a feather duster by the Press Complaints Commission).
I think this is a good thing. In real life people don't get fired for a first mistake, unless it is gross misconduct. If they are well managed, they get feedback and asked to put it right.
Reshuffles are a nightmare - ask Gisela Stuart who got forgotten in one of Tony Blair's reshuffles, or read the descriptions in the Blair or Jonathan Powell memoirs. The potential for chaos is legendary. Once, the then Chief Whip Archy Kirkwood and I went grovelling to the press gallery in Parliament to collect a press release about a reshuffle in which we had completely forgotten about someone senior.
I also think people should believe David Cameron when he says no Cabinet reshuffles this year. Can you imagine the resulting coverage? Lib Dem disappointment versus Tory back bench fury - the headlines would be entirely predictable.
A wise Tory backbencher said to me last week, "Why did Margaret Thatcher lose her leadership? Because if you put a tick by the names of every MP she had reshuffled out of government and of those who felt they had been overlooked that added up to the vote against her in the first round."
So save your money. Don't waste it on the flurry over the next few days about the departure of Lansley or the return of Laws. Beware the stories of reshuffles throughout the summer. Always ask yourself whether this was simply a slow news day?
Read Cameron's lips: no reshuffles this year. If only there were decent odds on that...
