President Donald Trump told electrical contractors Tuesday that his economic policies would translate into more jobs for their ranks as he highlighted a new trade deal among the U.S., Mexico and Canada.

"We're in the midst of a manufacturing renaissance — something which nobody thought you'd hear," Trump said in a speech to the National Electrical Contractors Association Convention in Philadelphia, a day after celebrating the new North American trade deal.

In fact, North America already is a manufacturing powerhouse. The United States ranks No. 2 in the world behind China in manufacturing output. Mexico ranks 11th and Canada 13th, according to United Nations numbers pulled together by the Brookings Institution.

Trump calls the new trade agreement USMCA, for U.S.-Mexico-Canada Agreement. "Like YMCA or U.S. Marine Corps with an A at the end," he explained.

He said he doesn't want to use the previous name, NAFTA, the North American Free Trade Agreement, which he contends cost American jobs and railed against during his 2016 presidential campaign. The new trade deal still must be approved by Congress.

"We are finally rebuilding our country, and we are doing it with American aluminum, American steel and with our great electrical contractors," he said.

Trump said the strong economy "means more jobs for our great electrical contractors."

Later Tuesday, Trump was heading to Southaven, Mississippi, across the border from Memphis, Tennessee, to campaign for Republican Sen. Cindy Hyde-Smith. Hyde-Smith was appointed to temporarily fill the seat held by Sen. Thad Cochran when he retired in April. She faces three challengers, including Democratic former Rep. Mike Espy, in the Nov. 6 special election.

Before departing the White House, Trump tweeted: "THE ONLY REASON TO VOTE FOR A DEMOCRAT IS IF YOU'RE TIRED OF WINNING!"
