Ten million more Americans will be eligible to vote in this November's presidential election than were eligible in 1976, and the majority of all eligible voters will be from the South and West, the Census Bureau reported.

According to the report, there will be 160 million Americans of voting age in November, 10.4 million more than 1976.

While the South and West now comprise 51 percent of voting-age Americans, voting patterns indicate these areas may not exercise that muscle. Both areas have fallen below the national average in voter turnout in past elections.

George Bush is taking his campaign to the airwaves in an uphill race to overtake Ronald Reagan, but technical problems knocked out the first five minutes of his Pennsylvania television show.

"Ask George Bush," a 30-minute program, was fed live to three central Pennsylvania television stations from a Lancaster, Pa., hotel convention room Friday night. The problems blacked out the first five minutes of the broadcast, but when the signal finally started coming through, the candidate was getting a standing ovation from an overflow crowd.

President Carter won 34 of South Carolina's 37 delegates at a state convention yesterday, with Sen. Edward M. Kennedy making virtually no effort to challenge him.

About 2,000 Democrats meeting in Columbia awarded Carter 23 delegates. Two others were elected as uncommitted and one went to Kennedy. Carter went on to carry all of the 11 delegates elected later in the day.

In Arizona by early this morning with 25 percent of the vote counted, Carter led with 49 percent to 42 percent for Kennedy. Voting was reported heavier than expected in precinct caucuses to elect 29 delegates to the national convention.

The Citizen's Party, holding its organizational convention in Cleveland, expects to nominate environmental scientist Barry Commoner as its presidential candidate.

Commoner, of Washington Univeristy, has been an opponent of nuclear power since the early 1950s. He said the party is more than merely a protest against the Republican and Democratic parties.

"Many of the people who are here have been protesting for so long that they have come to the view that the real way to deal with these issues is to get into political power," he said.

Commoner and his expected running mate, LaDonna Harris, wife of former Oklahoma senator Fred Harris, are attempting to get on the ballots in 30 states.

The party claims to have 3,400 dues-paying members and 14 chapters across the nation.

About 300 delegates and 200 alternates and observers are attending the session, which began Friday and ends tomorrow with the acceptance of a party platform.
