With primaries Tuesday in Texas, Ohio, Vermont and Rhode Island, Hillary Clinton and Barack Obama continue to spar over who is best suited to be the next commander in chief.
On the subject of national security, Clinton touts her experience — while Obama claims superior judgment as an opponent of the war in Iraq.
But speaking to reporters, Clinton said Obama's opposition to the war mainly amounted to a speech he gave in 2002. Reaching for a well-worn Texas metaphor, she called him "all hat and no cattle."
At a rally in Dallas, she said Obama was "unhappy" when she brought up national security: "If Sen. Obama doesn't want to debate me about national security, how's he going to debate Sen. McCain about national security?"
But Obama did want to debate Clinton — albeit long distance. Speaking in Providence, R.I., he argued that Clinton isn't the one to change American foreign policy: "Real change isn't voting for George Bush's war in Iraq and then telling the American people it was actually voting for more diplomacy."
As for the Republican candidates, Mike Huckabee visited the border town of Laredo, Texas, where he talked about illegal immigration. John McCain is spending the weekend at his ranch in Arizona. He could win enough delegates Tuesday to wrap up the nomination.
