They won't draw the huge numbers of daytime TV fans who follow "As the World Turns" or "Search for Tomorrow," but the people at WETA-Channel 26 are starting a show next week that residents around town have been following for more than four score and seven years - namely, the legislative effort to provide congressional representation for the people of the District of Columbia. At 9 a.m. Monday - live, from Capitol Hill (and with nary a commercial) - the station will begin gavel-to-gavel coverage of hearings conducted by the Senate Judiciary constitution sub-committee.

Host for this series will be subcommittee chairman Birch Bayh (D-Ind.), whose guest list will include a longtime sponsor of the legislation, Sen. Edward M. Kennedy (D-Mass.) and other congressional and administration supporters. Still other witnesses will appear at sessions on April 27 and 28. And if you'd like to be in the live audience, the hearings will be in Room 5110 of the Dirksen Office Building. Will this legislation finally make it through Congress after finally winning the necessary two-thirds vote in the House? And what about Republicans - will they provide crucial support for it the way they did in the House? How will Jimmy Carter shows his affection for the measure? Stay tuned . . .
