(Reuters) - Senator John McCain said on Thursday that he and other backers of immigration reform "are not winning," and must boost efforts to get the House of Representatives to pass such a bill.
McCain said proponents - who include businesses, churches and labor - will wage an aggressive campaign in selective congressional districts next month to make the case for a comprehensive overhaul of U.S. immigration laws.
"Here is a fact: We are not winning," the Arizona Republican told reporters. "So we have to wage a campaign. That doesn't mean a negative campaign. It means a positive campaign."
