With the Republican primary looming, George Allen is launching a two-week tour of Virginia as he seeks to lock down his party’s nomination for U.S. Senate.

Allen, the frontrunner in a four-candidate field for the GOP nod in the contest to succeed retiring Sen. James Webb (D), will make campaign stops Thursday with Lt. Gov. Bill Bolling (R) in Mount Jackson and Harrisonburg.

Those events are the start of Allen’s “Send a Message” tour, which his campaign describes as “a two-week tour rallying Virginians to send a message to President Obama, Tim Kaine and their Washington allies by giving George Allen an important victory in the Republican Primary on June 12.”

Allen has mostly focused his fire on fellow former governor Kaine, who faces no opposition for the Democratic nomination. But first Allen has to emerge from the June 12 Republican primary against Chesapeake minister E.W. Jackson, Del. Robert Marshall (Prince William) and former Virginia Tea Party Patriots head Jamie Radtke.

Kaine did an economic tour of the state with Sen. Mark Warner (D) earlier this year. His campaign noted Wednesday that he has now held 50 roundtable discussions since the start of 2012.
