U.S. Sen. Elizabeth Dole was very bipartisan in the 2005-06 session.

With the candidates for Senate touting their records of bipartisanship, Dome has been taking a closer look at the number of Democrats who signed on to legislation Dole sponsored.

In the 2005-06 session, the Salisbury Republican was the primary sponsor of 49 bills. Of them, 30 had no cosponsor, nine had only Republican cosponsors and nine had Democratic cosponsors.

Overall, her 63 cosponsors included 29 Democrats and 34 Republicans, or about a one-to-one ratio. (Dome is counting Sen. Jim Jeffords, an Independent, as a Democrat since he caucused with them.)

The most frequent Democratic cosponsor was Sen. Barbara Mikulski, who signed on to four Dole amendments, including a measure to require the National Academy of Sciences study drinking water contamination at Camp Lejeune.

Dole also had Democratic cosponsors on bills requiring a report on predatory lending to military families, assist worker retraining programs, encourage collectively bargained retiree health benefits, honoring a black Marine and giving a tax credit for hunger relief efforts.

How bipartisan has U.S. Sen. Elizabeth Dole been?

With the candidates for Senate touting their ability to bridge the partisan divide, Dome decided to take a closer look.

One measure is the number of Democrats who signed onto legislation Dole sponsored.

In the 2007-08 session, the Salisbury Republican was the primary sponsor of 75 bills. Of them, 42 had no cosponsor, 18 had only Republican cosponsors and 15 had Democratic cosponsors.

Overall, her 87 cosponsors included 64 Republicans and 23 Democrats, or about a three-to-one ratio.

The most frequent Democratic cosponsors were Sens. Joseph Lieberman and Ted Kennedy. Lieberman, an Independent who caucuses with the Democrats, signed on to bills praising the Coast Guard for a cocaine seizure, creating a student loan program for worker training and committing 4 percent of the gross domestic product to military spending.

Kennedy signed onto the Coast Guard resolution, an amendment that would require the Navy to publicize Camp Lejeune's drinking water contamination, and a resolution honoring the U.S. Marshals' anniversary.

Dole also had Democratic cosponsors on bills recognizing the Lumbee tribe, giving a tax credit for hunger relief, amending the Sarbanes-Oxley Act and the Trade Act of 1974, starting a pilot program for pregnant college students, honoring Veterans Day, creating a Southeast Crescent Authority and researching flow batteries.
