Virginia Democratic gubernatorial candidate Terry McAuliffe is linking himself to the landmark transportation compromise championed by Republican Gov. Robert F. McDonnell in his latest campaign ad, launching statewide on Wednesday.

The 30-second ad, titled “Too Important,” recounts the intra-party Republican fight over the legislation, and the bipartisan solution McAuliffe says he helped broker.

“February 22 ... A landmark transportation bill is up for consideration in the Virginia legislature,” the ad opens. “Even though it’s backed by Republican Gov. Bob McDonnell, tea party Republicans refuse to support the plan. But Terry McAuliffe thinks this is too important a time for partisan politics.”

The ad continues: “McAuliffe reaches out to Democrats and urges them to support the bill, and the bill passes.”

The spot ends with the message, “Terry McAuliffe ... Putting Virginia first.”

The transportation deal, expected to generate about $1.4 billion annually, is key to McDonnell’s legacy. The outgoing governor has been criticized by some Republican legislators and other fellow conservatives who viewed the plan as a tax hike.

The spot is McAuliffe’s second televised ad. The businessman and longtime Democratic fundraiser will challenge current Attorney General Ken Cuccinelli II to become Virginia’s next governor. The matchup is in the national spotlight as one of only two gubernatorial contests this year.
