It's not a better idea, because it is an impossible pipe dream, given the current political realities.
But it might be realistic if there is a very public walk-out that shakes the Party foundation and proves beyond a doubt that the GOPe faces certain political destruction if they don't choose the Conservative path.
I agree. Better to start something else, a Tea-Party/Don't Tread on Me type of thing that will grow and eventually siphon off what few conservatives remain in the GOP. The RINOs can just become dems in name as well as deed.
A third party is a great way to give the Rats a majority in both houses for a very long time. I don’t buy the argument that the GOP would “learn its lesson” from a massive walkout. Just look at the horror that we had when the Rats controlled both houses of Congress and the presidency in 2009-2011. And the GOP STILL voted with liberals time after time.
