All of the major Democratic and Republican candidates for president, plus political extremist Lyndon H. LaRouche Jr., qualified for spots on the Virginia primary ballot, according to Susan H. Fitz-Hugh, executive director of the state board of elections.

The deadline for filing was 5 p.m. Wednesday, and Fitz-Hugh said eight Democrats and six Republicans returned the required petitions of interest.

Fitz-Hugh told the House Privileges and Elections Committee yesterday that poll workers are being instructed to emphasize that although for the first time Virginia voters will have to choose a Republican or Democratic ballot, such action does not mean they are signing up as members of those parties.

"It just means that, for one day, they chose a Republican or Democrat ballot," Fitz-Hugh said.

In addition to Tennessee Sen. Albert Gore Jr. and LaRouche, Democrats on the ballot will be former Arizona governor Bruce E. Babbitt, Massachusetts Gov. Michael S. Dukakis, Missouri Rep. Richard A. Gephardt, Jesse L. Jackson, former Colorado senator Gary Hart and Illinois Sen. Paul Simon.

Republicans appearing on the Virginia ballot will be Vice President Bush, Kansas Sen. Robert J. Dole, former Delaware governor Pierre S. (Pete) du Pont IV, former secretary of state Alexander M. Haig Jr., New York Rep. Jack Kemp, and former television evangelist Pat Robertson of Virginia Beach.
