(CNN) - In his first press conference since two key losses over the weekend, John McCain said Monday he remains on track to be the Republican Party's nominee.
"We're doing fine. We're doing fine," the Arizona senator, who suffered losses in the Louisiana and Kansas caucuses and narrowly won Washington, said in Annapolis, Maryland.
"I am confident that we have and will continue our path toward getting the prerequisite number of delegates," he continued. "I am glad we have the support that we have - increasingly financial as well as political support from around the country."
McCain continues to hold a wide 437-delegate lead over Huckabee, and it remains nearly impossible for the former Arkansas governor to catch up in the delegate count.
But McCain has suffered some embarrassing setbacks in the days following Mitt Romney's decision to end his presidential bid. He drew a mixed reception at the Conservative Political Action Conference late last week, and has yet to score a convincing win since becoming the apparent GOP nominee.
His losses in Kansas and Louisiana were only tempered by a narrow win in Washington State – a victory that Huckabee is currently contesting. And the Arizona senator is continuing to have trouble uniting conservatives behind his candidacy: According to exit polls in Louisiana, conservatives broke for Huckabee over McCain by nearly 20 points.
"I have said we had a lot of work to do to unite the party," McCain said Monday. "Our party is dispirited because of spending and corruption, as we all know, and we have to reenergize our base."
