Haley will speak Friday night at an event expected to raise $300,000, said Pete Snyder, chairman of the Virginia Victory 2012 campaign. Tickets cost $90 with packages of tables and VIP tickets selling for $20,000.

Blunt will speak Saturday morning, though the prices are slightly lower. No fundraising estimates for that event were available, according to party officials.

Hundreds of activists are expected to attend the two events — some of the party’s biggest fundraisers during the crucial election year in which Virginia will help pick a president and determine the balance of power in the Senate.

Lt. Gov. Bill Bolling and Attorney General Ken Cuccinelli, rivals for the governor’s mansion next year, are expected to attend, according to their offices. Organizers also expected the GOP’s Senate nominee, likely George Allen, to be present days after the primary.

Gov. Bob McDonnell (R) will be on a trade mission to Europe and will not be there.

The state convention will draw about 3,000. Republicans will select delegates to the national convention in Tampa and revisit whether to hold a primary or convention for governor in 2013.
