This article explains why conservatives, who generally are more numerate than liberals, should reduce supporting their points with facts but rather move into the emotionally based realm. This would be the best way to overcome the liberal arguments.
"I am not advocating that we ignore and forget facts. They are stubborn things and in the long run tend to assume dominance in people's minds. But in the short term, conservatives must harness better emotional and rhetorical strategies if we are to prevail and save this country. Nothing should be off the table: rallies, impromptu conversations in supermarket lines, get-out-the-vote drives, involvement in our public schools, lawsuits, civil disobedience."
