So much for the grand promise of unity. Joe Biden's rush to erase Donald Trump from history delivered a forceful poke in the eye - some would say worse - to the 74 million people who voted for the other guy. Ironically, while the US Capitol riots were a disaster for Mr Trump and his legacy, they have also undermined Mr Biden's chances of bringing the country together in a post-Trump world. Cheered on by an increasingly noisy left wing of the Democrat party, demanding that all things Trump be cancelled, the new president spent his first hours in office doing just that. He is using everything available to him under his executive powers - what he can do without the approval of Congress - to wipe clean the last four years. But in doing so there has been no attempt to offer an olive branch to Republican voters, or their representatives in Congress. Senior Republicans have been taken aback by the extent of Mr Biden's opening measures, especially on immigration and climate change. Some took it as confirmation of their fears that the new president, a moderate Democrat, would end up a passenger in a party careering left. Mr Biden promised Mr Trump's voters he would work for them too. But so for there is little sign of it. And Republicans in Congress are nervous.
