Question: In which county is Millbrook located in the state where John Kerry's VP candidate was a senator?

<P0-S0> Millbrook, North Carolina, USA, was a village in Wake County at that time in the intersection of then Wake Forest Road and then Main Street, which is now part of East Millbrook Road. <P0-S1> However, the growth of Raleigh since the 1970s has swallowed up the village. <P0-S2> Milbrook High School in Raleigh is named after the village and is located in what used to be Millbrook. <SEP> <P1-S0> kerry and his second wife, mozambican-born businesswoman and philanthropist maria teresa thierstein simões ferreira (known as teresa), the widow of kerry's late pennsylvania republican senate colleague henry john heinz iii, were introduced to each other by heinz at an earth day rally in 1990. early the following year, senator heinz was killed in a plane crash near lower merion. <P1-S1> teresa has three sons from her previous marriage to heinz, henry john heinz iv, andré thierstein heinz, and christopher drake heinz. <P1-S2> heinz and kerry were married on may 26, 1995, in nantucket, massachusetts. <SEP> <P2-S0> federally, boston is split between two congressional districts. <P2-S1> the northern three-fourths of the city is in the 7th district, represented by mike capuano since 1998. the southern fourth is in the 8th district, represented by stephen lynch. <P2-S2> both are democrats; a republican has not represented a significant portion of boston in over a century. <P2-S3> the state's senior member of the united states senate is democrat elizabeth warren, first elected in 2012. the state's junior member of the united states senate is democrat ed markey, who was elected in 2013 to succeed john kerry after kerry's appointment and confirmation as the united states secretary of state. <SEP> <P3-S0> On July 6, John Kerry selected John Edwards as his running mate, shortly before the 2004 Democratic National Convention in Boston, held later that month. <P3-S1> Days before Kerry announced Edwards as his running mate, Kerry gave a short list of three candidates: Sen John Edwards, Rep Dick Gephardt, and Gov Tom Vilsack. <P3-S2> Heading into the convention, the Kerry/Edwards ticket unveiled their new slogan—a promise to make America "stronger at home and more respected in the world." <P3-S3> Kerry made his Vietnam War experience the prominent theme of the convention. <P3-S4> In accepting the nomination, he began his speech with, "I'm John Kerry and I'm reporting for duty." <P3-S5> He later delivered what may have been the speech's most memorable line when he said, "the future doesn't belong to fear, it belongs to freedom", a quote that later appeared in a Kerry/Edwards television advertisement. <SEP> <P4-S0> In the 2004 Democratic presidential primaries, John Kerry defeated several Democratic rivals, including Sen. John Edwards (D-North Carolina. <P4-S1> ), former Vermont Governor Howard Dean and retired Army General Wesley Clark. <P4-S2> His victory in the Iowa caucuses is widely believed to be the tipping point where Kerry revived his sagging campaign in New Hampshire and the February 3, 2004, primary states like Arizona, South Carolina and New Mexico. <P4-S3> Kerry then went on to win landslide victories in Nevada and Wisconsin. <P4-S4> Kerry thus won the Democratic nomination to run for President of the United States against incumbent George W. Bush. <P4-S5> On July 6, 2004, he announced his selection of John Edwards as his running mate. <P4-S6> Democratic strategist Bob Shrum, who was Kerry's 2004 campaign adviser, wrote an article in Time magazine claiming that after the election, Kerry had said that he wished he'd never picked Edwards, and that the two have since stopped speaking to each other. <P4-S7> In a subsequent appearance on ABC's This Week, Kerry refused to respond to Shrum's allegation, calling it a "ridiculous waste of time."
