Hey... we just had an intelligent conversation about politics!
On the union point, they will eventually cave. They have no leverage here, except threatening not to vote for Dems & President Obama in 2010 & 2012, which isn't much of a threat, if you ask me.
At this point, let's just hope this all works and the gov't can sort it out, get out of the auto business (and the finance business) and let whatever becomes of GM restore itself to its former prominence.
