Conservatives need to get back to good principles. Believing that people, not government, make America go. There's a lot of Black and Hispanic groups that have very conservative values but the left has done such a good job of painting Republicans as racists that they turn to the only thing left.
Many Black communities hate the welfare state - the way it encourages Husbandless - even "partner-less" welfare mothers who have more children to get bigger checks. Hispanic communities favor family values and hard work. They really aren't looking for a handout. My gay friend is fiscally very conservative and only votes Democrat because of he and his partner's personal issues.
If Republicans would get onto the fiscal responsibility angle, worked on keeping government off our phone calls and fighting for family values - that's families with parents, preferably two or more, raising children in good homes - they could get a lot of votes and retake power.
I think a majority of Americans don't want a large police state that tries to do everything.
