John McCain arrived in Annapolis this morning, one day before Maryland's presidential primary. But the Arizona senator seemed most interested in talking about the general election in November.

"We will compete in the state of Maryland when and if I am the nominee of the Republican party," McCain said at a news conference this morning at the Annapolis Marriott.

An enthusiastic crowd of nearly 1,000 people greeted former Arkansas governor Mike Huckabee today at the University of Maryland, where the presidential hopeful urged supporters to ignore "Beltway babble" about the Republican race being over and vote for him on Tuesday.

"Somebody forgot to tell you guys that there aren't any Republicans in Maryland," Huckabee told a crowd gathered at a student union on the College Park campus, which is hardly known as a cradle of conservatism. "This is incredible. ... I'm energized by you today."

Huckabee did not mention Arizona Sen. John McCain, the GOP frontrunner, by name during a speech in which he touted his plans to abolish the income tax and spoke at length about his humble upbringing.
