Question: When did voters from the state of the most successful American Idol contestant this season is from once again vote for someone from Mayor Turner's party?

<P0-S0> twelve senators from each state are elected for six-year terms, using proportional representation and the single transferable vote (known in australia as "quota-preferential voting": see australian electoral system), with half elected every three years. <P0-S1> in addition to the state senators, two senators are elected by voters from the northern territory (which for this purpose includes the indian ocean territories, christmas island and the cocos (keeling) islands), while another two senators are elected by the voters of the australian capital territory (which for this purpose includes the jervis bay territory). <P0-S2> senators from the territories are also elected using preferential voting, but their term of office is not fixed;  it starts on the day of a general election for the house of representatives and ends on the day before the next such election. <SEP> <P1-S0> Since the show's inception in 2002, ten of the fourteen Idol winners, including its first five, have come from the Southern United States. <P1-S1> A large number of other notable finalists during the series' run have also hailed from the American South, including Clay Aiken, Kellie Pickler, and Chris Daughtry, who are all from North Carolina. <P1-S2> In 2012, an analysis of the 131 contestants who have appeared in the finals of all seasons of the show up to that point found that 48% have some connection to the Southern United States. <SEP> <P2-S0> The city of Houston has a strong mayoral form of municipal government. <P2-S1> Houston is a home rule city and all municipal elections in the state of Texas are nonpartisan. <P2-S2> The City's elected officials are the mayor, city controller and 16 members of the Houston City Council. <P2-S3> The current mayor of Houston is Sylvester Turner, a Democrat elected on a nonpartisan ballot. <P2-S4> Houston's mayor serves as the city's chief administrator, executive officer, and official representative, and is responsible for the general management of the city and for seeing that all laws and ordinances are enforced. <SEP> <P3-S0> seattle's political culture is very liberal and progressive for the united states, with over 80% of the population voting for the democratic party. <P3-S1> all precincts in seattle voted for democratic party candidate barack obama in the 2012 presidential election. <P3-S2> in partisan elections for the washington state legislature and united states congress, nearly all elections are won by democrats. <P3-S3> seattle is considered the first major american city to elect a female mayor, bertha knight landes. <P3-S4> it has also elected an openly gay mayor, ed murray, and a socialist councillor, kshama sawant. <P3-S5> for the first time in united states history, an openly gay black woman was elected to public office when sherry harris was elected as a seattle city councillor in 1991. the majority of the current city council is female, while white men comprise a minority. <SEP> <P4-S0> North Carolina's party loyalties have undergone a series of important shifts in the last few years: While the 2010 midterms saw Tar Heel voters elect a bicameral Republican majority legislature for the first time in over a century, North Carolina has also become a Southern swing state in presidential races. <P4-S1> Since Southern Democrat Jimmy Carter's comfortable victory in the state in 1976, the state had consistently leaned Republican in presidential elections until Democrat Barack Obama narrowly won the state in 2008. <P4-S2> In the 1990s, Democrat Bill Clinton came within a point of winning the state in 1992 and also only narrowly lost the state in 1996. <P4-S3> In the early 2000s, Republican George W. Bush easily won the state by over 12 points, but by 2008, demographic shifts, population growth, and increased liberalization in heavily populated areas such as the Research Triangle, Charlotte, Greensboro, Winston-Salem, Fayetteville, and Asheville, propelled Barack Obama to victory in North Carolina, the first Democrat to win the state since 1976. <P4-S4> In 2012, North Carolina was again considered a competitive swing state, with the Democrats even holding their 2012 Democratic National Convention in Charlotte. <P4-S5> However, Republican Mitt Romney ultimately eked out a 2-point win in North Carolina, the only 2012 swing state that Obama lost, and one of only two states (along with Indiana) to flip from Obama in 2008 to the GOP in 2012. <SEP> <P5-S0> Despite being eliminated earlier in the season, Chris Daughtry (as lead of the band Daughtry) became the most successful recording artist from this season. <P5-S1> Other contestants, such as Hicks, McPhee, Bucky Covington, Mandisa, Kellie Pickler, and Elliott Yamin have had varying levels of success.
