If anything could cause a game change ahead of next Tuesday’s Republican U.S. Senate primary, it would be an endorsement from Attorney General Ken Cuccinelli.

Former Gov. George Allen is the clear front-runner in the four-way race, polling well ahead of Chesterfield County tea party activist Jamie Radtke, Chesapeake minister E.W. Jackson, and state Del. Robert G. Marshall, R-Prince William.

While most state heavyweights — like Gov. Bob McDonnell, Lt. Gov. Bill Bolling and House Majority Leader Eric Cantor, R-7th –- have already backed Allen, an endorsement from Cuccinelli, a tea party darling, could shake things up.

But Cuccinelli, whose opinion carries heavy weight among conservatives, has remained uncharacteristically silent on the race pitting Allen, an establishment figure, against three rivals courting tea party voters.

So could Cuccinelli be waiting to drop a last-minute bomb? Don’t hold your breath.

“It’s highly unlikely,” said Cuccinelli political director Noah Wall. “I don’t expect that Ken will get involved in the race.”

Asked if there was any reason Cuccinelli had decided not to weigh in, Wall responded: “We fully intend on supporting the nominees and making sure that we win Virginia this November.”

Cuccinelli also declined to make an endorsement in the Republican presidential primary.
