Arkansas Supreme Court Justice Courtney Goodson lost her bid to run the state's highest court two years ago after coming under fire from conservative groups that spent big on mailers and TV ads targeting her. Two years earlier, David Sterling was defeated in the race for the Republican attorney general nomination despite outside groups going after his rival in that race.

Now, the two are about to face off in what could wind up being another costly and heated fight for a state high court seat that could overshadow other races on the ballot this year. It could also turn into a proxy fight over the state's resumption of executions and the court's role in scaling back what had been an unprecedented plan to put eight men to death over an 11-day period.

Goodson quietly launched her campaign last week, with an adviser confirming that she planned to seek another term on the state's high court in the May judicial election. The same day, Sterling said he planned to challenge the incumbent jurist.

Neither candidate has laid out campaign arguments, but the past two election cycles offer some guide of what to expect. Goodson launched her bid for the chief justice seat ago vowing to represent "conservative values" on the court.

"The Supreme Court is supposed to represent your common sense, conservative values, to uphold the rule of law and to look out for your rights," Goodson said in a campaign video she posted in the fall of 2015.

A year earlier, Sterling was touting his conservative credentials in his campaign for attorney general and promised to use the office to protect Arkansans from "an overreaching federal government." Sterling lost in the runoff for the Republican nomination against Leslie Rutledge, who is now seeking re-election as the state's top attorney.
