Two-term incumbent Ralph Becker has nabbed high-profile posts while in office, serving as president of the National League of Cities and as one of President Barack Obama's appointees on a climate change task force. [...] while he's been in office, Salt Lake City has skewed more liberal and diverse, making it ripe ground for Democrats to square off, said Tim Chambless, a professor at the University of Utah's Hinckley Institute of Politics. [...] the state capital is its cultural and urban hub, home to a public research university and the young people and academics who follow. A Biskupski win would cap more than a year of strides for LGBT advocates in Utah after the legalization of same-sex marriage and the passage of an anti-discrimination law protecting gay and transgender people. Chambless said Becker, a former Democratic leader in the state House, has raised his national profile but is struggling because he's put in less face time with residents and local groups in recent years.
