From CBS News' Dante Higgins:
WASHINGTON, D.C. -- On the day of the Potomac primaries, John McCain is on Capitol Hill working to unite the party. And his campaign is confident they'll sweep all three contests - Maryland, Virginia and Washington, D.C. - tonight.
"We feel very good about today. I think we should win all three," said McCain advisor Charlie Black. "It could be that [Mike] Huckabee is stronger in Virginia, but going on public polls and common sense tells you we should win that one too."
Because Huckabee didn't spend money on advertising in these primaries, Black says they didn't feel the need to send McCain out into the field today. "We are doing a few get out the vote phone calls, but that's about it," he said.
Instead of poll station visits or last minute rallies, McCain is walking the halls his "day job" at the Capitol. He received a warm welcome and was the center of attention on the Senate floor this morning.
McCain met with the Senate Republican Conference today; a move that should help unite the party behind him. Tomorrow, he will have a similar meeting with Republican members of the House.
