In February 1980, the House Administration Committee voted 11-7 to reject Wilson's call for the unseating of Leach. The vote mirrored party alignment, with all Democrats voting to dismiss, and each Republican favoring continuance of the investigation. Finally, on March 4, 1980, the full House voted 241-153 to drop Wilson's challenge. Leach's Democratic colleagues from Louisiana, Thomas Gerald "Jerry" Huckaby, Gillis William Long, [[John Breaux]], and Lindy Boggs all voted to dismiss, but the three Louisiana Republican congressmen, [[David C. Treen]], William Henson Moore, and Robert L. "Bob" Livingston abstained. A handful of Republicans voted with Leach, and a handful of Democrats sided with Wilson's allegations.
==Running again in 1980==
Rebuffed by Congress, Wilson announced on April 30, 1980, Statehood Day in Louisiana, that he would challenge Leach in the 1980 nonpartisan blanket primary. A ''Shreveport Journal'' showed Wilson with a slim lead at the time in a potential re-run of a race against Leach. There was, however, a large bloc of uncommitted voters. Wilson said that he expected to raise and spend $500,000 for the second race because national Republicans had again targeted the 4th district as one of thirty-five in the nation where the GOP stood a chance of winning a Democratic seat.
