Hawkins urges the GOP not to purge the party of the social conservative wing. I agree the GOP needs to be a tent that tries to include as many people as possible. So they should also appeal to libertarians and ethnic voters. Maybe they need HM Minister Jason kenney to advise them.
If the GOP is going to tell 26% of American voters to take a hike, who, pray tell, are we going to replace them with? The 500,000 people who voted for Bob Barr? Maybe we can get Scott McClellan, Colin Powell, and Christopher Buckley to start voting Republican again. That's not quite 26%, but it's a start, right?
It's also worth noting that if the GOP wants to reach out to demographic groups that we're not doing very well with, like Hispanics and black Americans, socially conservative issues are one of the best ways to do it. "About one-third of Catholics in the United States are now Hispanic." Moreover, 90% of Hispanics are members of some branch of the Christian faith. The same goes for black Americans, "85 percent (of whom) say religion is very important in their lives."
All that being said, I will grant you social conservatism can be a loser if it comes across as preachy, bossy, or overdone. Moreover, there is a weird discomfort some people have about Christians who are serious about their faith getting interested in government. However, Christians had better be interested in the government because the government is certainly interested in them. It's interested in shaping the minds of their children, it's interested in shaping the culture around them, and it's interested in shaping who gets to be married in their church. If people of faith are willing to help the GOP in return for having their interests protected in Washington, the Republican Party would be extraordinarily foolish to turn them away.
