Doesn't the GOP need to jettison the social conservatism and focus solely on the fiscal conservatism?

[Number]

If you do that the entire party becomes out of touch with the rest of America.
What makes a party like the Democrats have so much power?
They keep in touch with several single issue groups like Feminists, Gays, Liberals, Environ-nutjobs, Poor folk, etc
They also attract people when the liberal media works to get a reaction
Anger works in the Democrat's favor, thus winning them seats
If the Republicans decide to cut and run from its Evangelicals
There wouldn't be such strong support anymore
Social conservatives would form their own third party, splintering the old GOP
GOP needs some of its agenda to be passed so they keep the Christians around to be in power
