[A conservative party would never, ever win elections. Not one.]
Disagree on this point. Pubs lost because they abandoned moral values and are the friends of liberal democrats and their socialist one world agenda of government is your parent mentality.

To win elections in America, you need to appeal to a great diversity of voters.
A conservative party would not. They would lose.
Now, in some portions of the country, they could win local elections.
