Senate candidate George Allen reached out to social conservatives last week in his first piece of direct mail in Virginia.

The mailer cited endorsements by state conservatives and reminded voters — with pictures of smiling babies and text — that Allen signed a parental notification bill as governor that required doctors to inform parents before performing an abortion on a minor.

“As Governor and Senator, George Allen has a proven record of standing up for our families and unborn children,” the mailer states, citing his co-sponsorship of the ban on partial birth abortion.

Democratic sources noted that the mailer proves Allen is concerned about a primary challenge from the right. The mailer was first reported by conservative political blog Bearing Drift.
