Run out of endorsement opportunities in one state? Try another.

Businessman Bob Dold looked next door after a rival candidate in the Feb. 2 primary locked up endorsements from the Illinois Republicans he hopes to join in Congress.

Dold — who’s going after the seat being vacated by Rep. Mark Kirk — announced the endorsement of Indiana Sen. Richard Lugar.

No, Lugar doesn’t represent anyone who’ll be voting in the primary, but he does have stature within the GOP, and his support lets Dold demonstrate backing by national Republicans.

Last week, the Dold campaign rolled out the endorsement of another name that will be familiar to primary voters: his ex-boss, former Vice President Dan Quayle.
