Republican presidential nominee Mitt Romney will extend his swing through battleground Virginia, making a campaign stop in Loudoun County on Wednesday.

Romney is holding an event in the Roanoke area tomorrow, appearing at Carter Machinery in Salem.

On Wednesday afternoon, he’ll hold an event in Sterling at EIT LLC, an electronic design and production services company. 

Northern Virginia and the Roanoke-Lynchburg area will both be critical regions of the state in November’s election.

Romney made two campaign stops in Virginia in early May, holding events in Chantilly and Portsmouth. He also delivered the commencement address at Liberty University in Lynchburg. President Barack Obama officially kicked off his reelection effort in Richmond last month.
