Notice that no matter how far to the Left their side gets, they are never presented as "extremists" or "Whackos". Heck, even our own side tends to kick the dog crap out of anyone who suggests return to original intent.
How in the heck are we going to win doing their work for them?
We can't out Democrat the Democrats, can't out Liberal the Liberals, and for d@mned sure can't give away more than they do, but the novel tactic of appealing to the base might work, if it was tried.
Had Romney's bunch decided to remind Catholics of their ties to a Church that would not budge on gay marriage nor abortion/obamacare, maybe they could have brought in more votes, especially from the Hispanic Catholics (run the ads in Spanish, in the appropriate market areas). Put the fear of God in the voters, where it counts. That could have been an entire ad campaign, and that is just one instance of where fighting the good fight might have made a difference.
