What Obama's piqued-ness at his press conference reveals - and a press conference is hardly the first, best way to make yourself look "Presidential", to assert 'The Presidential Voice' - is that they think they've done an exceptional job running the government.
In some ways they have. They've been very good on appointments, with little scandal, but also at the cost of time. They've done an exceptional amount, while also running two hot war zones, something truly great.
But, the truth is that a generic Democratic candidate would have enjoyed large majorities in the House and Senate in 2008. Therefore, things like healthcare reform may not be so much attributable to the unique skills of Obama. Hillary or even Biden probably could have gotten the same.
What he was elected to do qua Obama was to bring a refreshing responsibility to governance, in a clear departure, a clean break from the ways of Bush-43, to offer audacity of perspective and to continue to inspire people to a new way forward.
Have they delivered on that? Is that too much to ask, even during hard times?
