Who in the GOP pays you for saying such crap? ... The GOP/RNC cannot be reformed - they have to be sidestepped... and done away with eventually ... It is not a matter of leaving the GOP they have left Conservatives ... the Core of the Republican Party and spit upon us... In a few years the current GOP will be history and they become more like the Democrat Party of a few years ago ... The GOP will be replaced - not reformed...
I pretty much agree with you, in principle. The current GOP leaders are out for themselves, and they care about nothing else. But it will take time to form a viable third party. And even more time to get that party strong financially.
During that organizational time, the far-left will have an uninterrupted stay at the White House, where they will do enormous, perhaps irreparable, damage. Sadly, it's not like the early 1800's, when the federal government was weaker.
Perhaps I'm being too pessimistic, but that's the way I see it. Realistically, our best chance is reform from within.
But wait...there is another path. If somehow we could reform election law to allow for run-offs, then a third party would make very good sense.
