won by a wide margin despite the Democrats' 551,000-voter registration advantage statewide. Heinz died in an airplane crash on April 4, 1991, in Lower Merion Township, Pennsylvania. Democrat Harris Wofford was appointed on May 8 to fill the vacancy caused by Heinz's death, and subsequently won a special election in November 1991. In the 1994 election, however, Wofford was defeated by Republican Rick Santorum. Rhode Island Incumbent Republican John Chafee won re-election to a third term, beating Democratic lieutenant governor and former state senator Richard Licht. Tennessee Incumbent Democrat Jim Sasser won re-election to a third term over Republican Bill Anderson. Texas Incumbent Democrat Lloyd Bentsen won re-election to a fourth term defeating Republican Representative Beau Boulter. Bentsen easily won the Democratic nomination for another term, while Boulter came through a run-off in the Republican primary defeating Wes Gilbreath. After being nominated for the senate Bentsen was chosen by Michael Dukakis as his vice-presidential running mate and therefore ran for both the Senate and the vice-presidency at the same time. Bentsen was always the favorite for the senate election and won with 59.2% of the vote, compared to 40% for Boulter. As of 2020, this was the last time a Democrat won a United States Senate election in Texas. In the Democratic primary Democratic senator Lloyd Bentsen defeated the same opponent he had beaten in 1982, Joe Sullivan, a psychology professor from San Antonio.

He was also Chairman of the Senate Finance Committee and the clear favourite for re-election in 1988. Sullivan stood on a platform calling for reduced spending by the federal government, but had been easily defeated by Bentsen in the 1982 Democratic primary. This was repeated in 1988 with Bentsen winning the primary with over 80% of the vote. Four candidates competed for the Republican nomination; U.S. representative Beau Boulter, former state representative Milton Fox, millionaire Houston businessman Wes Gilbreath and businessman Ned Snead. Boulter was a two-term representative for the 13th district, while Gilbreath was competing in his first election, but spent $500,000 on the primary. Wes Gilbreath led in the March primary with 36.7%, but as no candidate won a majority, went into a run-off election against Beau Boulter who came second with 30.5%. There were few policy differences between Boulter and Gilbreath, with both
