The idea you are talking about is plainly referred to as a "wedge issue". You bring up a great point. This could be a pivital idea for the GOP, IF they use it to their advantage.
The GOP in general has a difficult time getting their message out becuase of the establishment media. Their paralysis of effort is confounding. There are times to wait and there are times to strike. Let us pray the 'Pub leadership can figure it out.
Correct assessment. What could be better for the Right than a fight between the thousands of special interests that make up the Democrat Party? We must make one of their constituent groups a millstone about their necks.
