That’s a proposal to create a geographically regional party that will consistently nominate presidential candidates to the right of the general electorate.
In a parliamentary system, such a party can wield considerable influence by coalition.
But in ours, where a simple majority allows a party to set the agenda in Congress and the president is elected by a system that roughly mirrors the popular vote, such a party has to depend on the opposition to consistently nominate weak candidates and consistently do politically stupid things.
IMO the best such a party could hope for would be to find itself in the position of the “Dixiecrats”, and that only worked because racism was an electoral glue stronger that other sorts of self-interest - a situation not likely to be repeated on the basis of current issues.
I am SICK of hearing this spineless “we must present the people with our own socialist to defeat the other socialists” drivel!
Grow a spine and take a stand for something beside politics as usual!
