The ongoing debate over Syria will not be the defining issue of the 2014 midterm elections, Democratic Congressional Campaign Committee Chairman Rep. Steve Israel (D-N.Y.) said Tuesday.

Speaking to reporters at a Christian Science Monitor breakfast in Washington, Israel said the election will pivot on "the middle class," which political party presents "solutions," and competing visions over President Obama's health care law.

"It will be referendum not on Obamacare, but on who is trying to make it work and who is trying to destroy it," said Israel.
