Former New York Mayor Rudy Giuliani will campaign for Romney in Virginia this week.

Next week, New Jersey Gov. Chris Christie will travel to the region -- likely the District -- on behalf of the former Massachusetts governor.

Romney recently opened a dozen new offices in the state and recruited volunteers at nearly 30 events on July Fourth. Read our full story from Sunday.

Romney is scheduled to appear on “The John Fredericks Radio Show” on WHKT-AM 1650 in Hampton Roads Tuesday.

Political observers think it’s possible that President Obama could win the general election without carrying Virginia, but the state remains crucial for Romney’s election hopes.

Giuliani will headline a veterans event in Virginia Beach Thursday and the grand opening of the Henrico County campaign office Friday, along with Lt. Gov. Bill Bolling (R).

Details on the Christie event were not available.
