Two weeks ago Barack Obama opted out of the public finance system for elections even though he had previously, in writing, pledged not to do so.
During his contest with Hillary Clinton be backed Democrat opposition to President Bush's efforts to protect telecoms companies who had been part of a wiretaps programme. Last week he dropped his opposition.
He has long supported the handgun ban in Washington DC but has now backed the Supreme Court's overturning of that ban.
He has also flip-flopped on whether the death penalty could be used for the rape of a child. Once opposed he now sees such a penalty as "potentially applicable".
These and other positions are examined in a brilliant piece from Dominic Lawson in this morning's Independent. I expect Senator Obama will soon be adjusting his position on Iraq soon, too - retreating from any speedy withdrawal of troops.
Are these position changes genuine? Will he hold to the changed positions in office? What do they tell us about Barack Obama's ideological maturity? Electing the hugely inexperienced one term Senator from illinois will be the greatest of electoral gambles.
