Let me flip the argument around on you. Do we have time to reform the Republican Party that has resisted reform since 1980, for 40 long years? Republicans fought Reagan hard to blunt his agenda and then forced the Bush Crime Family upon us. The GOP is irredeemable.
It is time to pull a Hernan Cortez and burn our ships on the shore and to march west into the unknown.
A third party will go nowhere. Do the math. There are not enough of us.
