Senior Americans have called for Assange to be killed which alone should be enough to rule out any extradition.
Personally I feel we should not extradite anyone to the US except perhaps fleeing American criminals. I think the UK–US extradition treaty of 2003 should be rescinded. It's utterly one sided so a betrayal of British sovereignty. If I commit a crime on British soil then I should be charged in a British court and imprisoned in a British prison, not sent off to a politicised [judges should not be elected or appointed by the head of state] US court and sent to their privatised rape gulags.
Assange has not committed a crime in the US. He has said he is willing to spend time in an English prison for skipping bail, or even be extradited to Sweden, as long as he is assured he will not be extradited to the US which has a long and ongoing history of political show trials [Manning, Winner, and potentially Snowden].
I'm not an Assange fanbois, I think he disgraced Wikileaks with his attempt at election meddling, but I resent the expense of policing him in the embassy and wish a sensible UK politician or judge would guarantee no extradition to the US as a compromise out of this ridiculous stalemate. Even Soviet Hungary eventually gave József Mindszenty safe passage
