Lots of people say they don't like the choices but the only viable alternatives at this point would be the Libertarian and Green candidacies as these minor parties are on all or nearly all state ballots.
The Libertarians have the most mainstream ticket with two former GOP governors in Gary Johnson of NM and Bill Weld of MA..
They need a strategy to get from footnote to double digits as the two party debate duopoly stands in their way.
Johnson is polling at about 8 points but higher in some states,
With a pair of unpopular major party hopefulls, the Johnson-Weld ticket is worth keeping an eye on.
