Hayworth offered a lukewarm concession speech after losing his Senate primary battle to Sen. John McCain."](CNN) - After J.D. Hayworth's bid for the Senate in Arizona and Bill McCollum's bid for the governor's mansion in Florida each came to an unsatisfying end, the two candidates offered lukewarm concessions that highlight how divisive each race had become.
McCollum, Florida's attorney general and the GOP establishment's pick who lost to former insurance executive Rick Scott in Florida, conceded the race at almost 1 a.m. via a press release.
"No one could have anticipated the entrance of a multimillionaire with a questionable past who shattered campaign spending records and spent more in four months than has ever been spent in a primary race here in Florida," McCollum said.
"While I was disappointed with the negative tone of the race, I couldn't be more proud of our campaign and our supporters for fighting back against false and misleading advertising when we were down by double-digits," he added.
In Arizona, Hayworth, a former congressman and conservative talk radio host, was handed a 25-point loss by Sen. John McCain, who spent more than $20 million to defend his seat. In his concession speech, he offered a call to move forward, albeit unhappily.
"And now the people of Arizona, conservatives and Republicans apparently believe our senior senator [McCain] will move to secure the border," Hayworth said to jeers from his supporters. "Let's understand we need to move forward, the time for derision in the campaign is beyond us."
Hayworth said that "without sarcasm or derision or delusion…Our fellow Arizonans do believe the incumbent will be a better custodian of their goals and desires, and we earnestly hope that will be the case."
McCain will face off against former Tucson vice-mayor Rodney Glassman, who secured the Democratic nomination on Tuesday night. Scott will face Democratic gubernatorial candidate Alex Sink in the general election.
