Hotline On Call

In the Hawaii Senate race, former Republican Gov. Linda Lingle likes to tout her commitment to bipartisanship -- but it's Democratic Rep. Mazie Hirono who just got an unusual aisle-crossing endorsement.

Alaska Rep. Don Young appears in a 90-second video endorsing Hirono in her primary contest with former Rep. Ed Case.

Young says that while the two lawmakers "don't see eye to eye on everything, we've done something too many people in Washington refuse to cross the aisle and do: we've worked together."

Hirono says she had to "battle my own party leadership" to get an amendment their passed.

The two joke around in the spot, with Young calling House Minority Leader Nancy Pelosi "one stubborn -- " before Hirono cuts him off. He then attempts twice more to remark on the California Democrat, with Hirono stopping him each time.

The ad and endorsement are likely aimed at taking wind out of Case's sails on his argument that Hirono is too liberal to effectively represent the state. And looking ahead to the general, it's clear Hirono wouldn't cede the "bipartisan" ground to Lingle.

The Democratic primary is August 11.
