Hopefully he uses his last few years to put several tons of TNT under the Capitol building's foundation.

That unfortunately can't be successful without major country wide electoral reform to remove first past the post style voting. I could only really see that happening if the capitalists think that they need to destroy the current two party system to get better control of worsening conditions. Basically asking the masses to calm down and they can vote some greens and libertarians into power as a treat.

If he was willing and prepared to do that then he should have spent the last 8 years doing so.

Unless he admits to having acted like a coward and an opportunist then there's no reason for anybody to trust him, he switches effortlessly between closing blue ranks and offering carefully measured critiques that will permit him to stay at the table.
