Topeka — Rick Santorum has left the Republican presidential race, but the Kansas delegates he won in the state's GOP caucuses aren't yet free to declare their support for presumed nominee Mitt Romney.
Kansas Republican Party officials say they're waiting for official word from Santorum's now-suspended campaign on whether he'll release his delegates from their commitment to vote for him at the GOP national convention.
The former Pennsylvania senator won the March 10 caucuses in Kansas and claimed 33 of the state's 40 convention delegates. The rest went to Romney.
The Kansas GOP will finish picking the delegates April 28. Several who've already been selected told The Associated Press that they still feel bound to Santorum until he releases them.
