Virginia’s first lady, Maureen McDonnell, whose husband is rumored to be on Romney’s possible VP list, is expected to attend.

Ann Romney, who has battled multiple sclerosis, has been a popular figure on the campaign trail. She made headlines Wednesday for taking to Twitter to refute a criticism that she “never worked a day in her life.”

Pete Snyder, chairman of the Va Victory 2012 campaign — the GOP’s coordinated campaign — said the event will bring in more than $300,000 — expected to be the largest amount ever for a Republican candidate’s wife.

Yes, the women will present Romney with a birthday cake. Shhhh. It’s supposed to be a surprise.
