Question: Who did Bruce Herschenohn run against in his primary? Passage:In 1992 four-term incumbent Democratic Senator Alan Cranston retired, creating an open seat contest. In what was billed as the "Year of the Woman", Boxer beat fellow Rep. Mel Levine and Lieutenant Governor Leo McCarthy in the Democratic primary, winning 44% of the vote. In the general election, Boxer defeated Republican Bruce Herschensohn, a conservative television political commentator from Los Angeles, by 4.9%. A last-minute revelation that Herschensohn had attended a strip club at least partially affected the outcome. In 1998, she won a second term, beating sitting California State Treasurer Matt Fong by 10.1% of the vote. After facing no primary opposition in the 2004 election, Boxer defeated GOP candidate Bill Jones, the former California Secretary of State, by 20%. In 2010, Boxer defeated GOP candidate Carly Fiorina, former chief executive officer of Hewlett-Packard, by 10%.

Question: What was the former name of the Blohmn & Voss aircraft division? Passage:Soon after the start of World War II, it was proposed to convert the four prototypes to long-range maritime patrol aircraft. V2 underwent a trial modification. It was fitted with an extended nose section with extensive glazing (like the Heinkel He 111 H-6), defensive armament (a 7.92 mm/.312 in MG 15 machine gun in the nose, twin-beam positions, a ventral cupola, and a powered dorsal turret), a compartment for ordnance in the fuselage, and navigation and military radio equipment. The company had by now been renamed as the Blohm & Voss aircraft division so the converted aircraft was redesignated the BV 142 V2/U1 while the V1 was similarly converted. Both were used operationally from late 1940 and were posted to the Luftwaffes second surveillance Group. This unit was assigned to the operations staff of Luftflotte III in France. However, their performance was disappointing, and after only a few missions they were withdrawn from service in 1942. Aircraft V3 and V4 were used as transport aircraft for the occupation of Denmark and in the Norway campaign with the KGr.z.b.V. 105 (Special combat team) and could transport 30 fully equipped soldiers over 4,000 km (2,490 mi). The ultimate fate of V3 and V4 is unknown. It was later planned to use the V1 and V2 to carry the Henschel GT 1200C guided torpedo, but the plan was cancelled.
