FRANKFORT — Democratic U.S. Senate candidate Alison Lundergan Grimes is calling on President Barack Obama to approve the Keystone XL oil pipeline, joining 11 incumbent Democrats as the party tries to keep control of the Senate this November.Grimes' statement Wednesday came on the same day a group committed to blocking the pipeline's construction announced plans to spend $500,000 setting up field offices in Kentucky to defeat U.S. Sen. Mitch McConnell. And it comes after McConnell and Republican Party officials have repeatedly criticized Grimes for delaying her opinion on the project, which has become a key issue in Senate races across the country.The Keystone pipeline would transport crude oil from Canada through Montana, South Dakota and Nebraska before linking up with existing pipelines. It would not cross through Kentucky.
