Ron Paul is, above all, patient.

As the Presidential candidate of the Libertarian Party, Dr. Paul knows he will do well to get 2 percent of the vote on Nov. 8. Still, the 53-year-old physician and former Congressman continues to travel the country virtually without a break, trying to get into newspapers and on television, giving speeches and preaching his party's philosophy of ''get the Government off our backs'' to students at colleges and high schools.

''Get rid of the personal income tax,'' he declared at the University of Houston recently. Then he added: Bring American troops home, abolish the Federal Bureau of Investigation and the Central Intelligence Agency and dismantle every other agency except the Justice and Defense Departments.

Dr. Paul, reflecting on politics in a recent interview during his swing through Houston, said the school visits are just as important as the rest of the campaign. It did not seem to bother him that only 10 of about 300 students he addressed at a high school near Houston were old enough to vote and only 5 were registered. Building for the Future

''We're building the Libertarian Party and we're just as interested in the future generation as this election,'' said Dr. Paul, a slight, gray-haired obstetrician from Lake Jackson, Tex. ''These kids will vote eventually, and maybe, just maybe, they'll go home and talk to their parents.''
