Politico:

Former Virginia Sen. George Allen is taking increasingly aggressive steps to lay the groundwork for a 2012 Senate comeback.
POLITICO has learned that Allen, the Republican who was ousted from his seat in 2006 by Democratic Sen. Jim Webb, recently huddled with National Republican Senatorial Committee Chairman John Cornyn to discuss a prospective bid. He is also burnishing his profile through a series of public events, spreading cash through his political action committee and has even launched a Facebook page.
According to one source familiar with Allen’s efforts, he sent a strong signal to other ambitious state pols by informing GOP members of the Virginia congressional delegation in early 2010 that he was thinking of running for Senate.
