Sarah Palin is due to accept her nomination in a highly anticipated prime-time speech, intended to introduce the Alaska governor to the American people.
McCain and Palin received rousing endorsements from prominent supporters, including President George Bush, during the convention on Tuesday.
Speaking via satellite from the White House, Mr. Bush said McCain understands the need to keep the United States safe from potential terrorist attacks. He also praised McCain for supporting the surge of American troops in Iraq.
Senator Joe Lieberman, the Democratic Party's vice presidential nominee in 2000 who is now an independent, told delegates that he supports McCain because "country matters more than party." He also criticized Democratic presidential nominee Barack Obama, saying he has not reached across party lines to accomplish anything significant during his three-and-a-half years in the Senate.
Former Republican presidential candidate and ex-Senator Fred Thompson paid tribute to McCain's long political and military service, telling delegates that McCain, a former prisoner of war in Vietnam, has the courage the country needs. He also slammed Obama, calling him the most liberal and inexperienced nominee ever to run for president.
Tuesday was day two of the Republican convention and focused on McCain's service to the country. Monday's abbreviated session spotlighted Hurricane Gustav and efforts to help affected residents in the Gulf Coast.
All eyes will be on Palin tonight during her acceptance speech. She has kept a low profile since McCain introduced her as his running mate last week, in the wake of revelations about her pregnant, unmarried teenaged daughter, and an ethics investigation in Alaska involving the firing of a state official.
McCain has said he is pleased to have Palin as his running mate. And she has garnered strong support among Republicans for her anti-abortion stance and social conservative views.
Obama said earlier this week that the candidates' families should not be the focus of politics, a view shared Tuesday by his running mate, Delaware Senator Joe Biden.
John McCain is to accept the Republican party nomination Thursday.
