Former U.S. President Bill Clinton spoke with top Democratic donors at a private meeting on Saturday where, according to Politico, he warned the group to treat gun control differently than other political issues.

“Do not patronize the passionate supporters of your opponents by looking down your nose at them,” Clinton reportedly said.  “A lot of these people live in a world very different from the world lived in by the people proposing these things…”

He proceeded to explain how, though polling data is certainly useful for politicians, it doesn’t measure the emotion and enthusiasm associated with an issue.  And it’s the passion associated with gun control, Clinton argued, that makes it so delicate.

Politico continues:

Clinton dedicated a substantial portion of his 40-minute address before a joint meeting of the Obama National Finance Committee and a group of business leaders to the issue of guns and gun control, saying that it was a test-case for President Barack Obama’s grass-roots movements…

“The way the Obama campaign won Florida, won Ohio, won this election by more than projected was the combination of technology, social media and personal contact,” Clinton said. That’s “the only way that our side will ever be able to even up the votes in the midterms and as these issues come up, really touch people and talk to them about it.”
