Former Vice President Dan Quayle has waded into another competitive GOP primary this week, endorsing businessman Bob Dold (R) in the multi-candidate race for Rep. Mark Kirk’s (R-Ill.) seat.

“Bob is the right candidate at the right time for the Republican Party,” Quayle said in a statement from the Dold campaign.

Dold is one of several candidates looking to succeed Kirk as the GOP nominee in the Feb. 2 primary, including businessman Dick Green and state Rep. Beth Coulson. Democrats have indicated that they plan to target the district, and marketing consultant Dan Seals — their 2006 and 2008 nominee — and state Rep. Julie Hamos are running for the Democratic nod next month.

This is the second time Quayle has endorsed a candidate this week. He endorsed 1996 gubernatorial candidate Ovide Lamontagne’s (R) bid for the open New Hampshire Senate seat — another competitive, multi-candidate primary. Quayle also endorsed Todd Young‘s (R) bid last October for Rep. Baron Hill’s (D-Ind.) seat, however Young is related by marriage to the former Vice President.
