President Bill Clinton is urging Democrats in Pennsylvania's 13th Congressional District to vote in Tuesday's primary for Marjorie Margolies, whose crucial vote in the House saved his economic plan two decades ago.

"She knows we need to raise the minimum wage, fight for equal pay for women, strengthen Social Security and Medicare, and make sure all our children get a chance to have a good start by investing in education," Clinton says in a recording that Margolies' campaign will dial into Democrats' homes in the final hours before the vote.

Margolies, 71, cast the deciding vote in Congress as a U.S. House member in 1993 for Clinton's budget framework; it raised taxes and she was bounced by the voters of the district the next year in the wave midterm election that gave Republicans control of the House for the first time in four decades.

Her vote "reversed trickle-down economics and set the country on the longest peacetime expansion in history – one that all Americans participated in," Clinton says in the recording. "That's what we've got to do again," he says. "We've got to get our country back into the future business."

Margolies, whose son is married to Chelsea Clinton, the president's daughter, faces a tough primary race against state Rep. Brendan Boyle of Northeast Philadelphia, state Sen. Daylin Leach of Montgomery County, and Val Arkoosh, an anesthesiologist and Democratic activist from Montgomery County.

The district straddles Montgomery’s inner-ring suburbs and the city’s Northeast. The seat is becoming vacant because U.S. Rep. Allyson Schwartz is running for the party’s nomination for governor.
