Kansas City, Mo. ? Republican presidential candidate Ron Paul is planning a stop in Kansas City.

Paul, who finished second behind Mitt Romney in last weekend’s Maine primary, is widely considered to be trailing Romney and Rick Santorum in the race for the Republican nomination.

But Paul says he remains a viable candidate, and he’s planned a rally Saturday night at Kansas City’s Union Station to mobilize supporters before the state’s March 17 Republican caucuses.

Paul finished third behind Santorum and Romney in the official Missouri primary Feb. 7, but a series of political spats prompted the GOP to ignore the results and instead begin picking delegates from the caucuses.
