Retiring state Sen. Patsy Ticer (D-Alexandria) has endorsed Arlington School Board member Libby Garvey to replace her in November, according to Garvey’s campaign.

In a statement, Ticer says Garvey is a “fast study and is committed to the issues important to me.”

Garvey’s campaign says Ticer will participate in a campaign kick-off event in April.

Though the exact boundaries of the senate district will not be clear until redistricting is completed next month, the Arlington/Alexandria area that Ticer has represented has been one of the state’s most reliable Democratic. For that reason, the November election outcome will likely be determined by the August 23 Democratic primary.

A tough race is shaping up for the Democratic nod between Garvey, Del. Adam Ebbin (D-Alexandria) and Alexandria City Council member Rob Krupicka.

Ticer had suggested she was likely to endorse Garvey when she announced last month that she did not plan to run for reelection, indicating that she would prefer to be replaced by a woman so the number of women in the state senate did not dip with her retirement. But she said then that she knew all three likely candidates and respected each.

In a statement Garvey called Ticer a “role model” and she hoped to “continue her legacy of style and grace” in the state senate.
