(CNN) - The presidential campaigns are pushing for votes in key battleground states Saturday as the race for the White House enters its final weekend.
Republican nominee Sen. John McCain, trying to make up a deficit in many polls, appeared at a rally Saturday morning in Newport News, Virginia, a formerly reliable Republican state that has become a toss-up.
McCain told the crowd that his Democratic opponent, Sen. Barack Obama would try to raise taxes as president.
"He's running for redistributor in chief, I'm running for commander in chief," McCain said to supporters' cheers.
McCain is due later in Springfield, Virginia, and Perkasie, Pennsylvania, before heading to New York City for a scheduled appearance on "Saturday Night Live."
Obama will start his day with a morning rally in Henderson, Nevada, before moving on to Pueblo, Colorado, and a late-night rally in Springfield, Missouri.
