If you're part of the rapidly shrinking Venn diagram intersection of "people who care about what Joe Arpaio thinks" and "people who still think Rick Perry will win the Republican nomination", here's some news for you:

Sheriff Joe Arpaio, a well-known immigration hardliner, will endorse GOP presidential candidate Rick Perry by the end of the week, NBC News reported this weekend.

Perry, who has been criticized by other Republicans for being too lenient on illegal immigration, will continue his campaign in New Hampshire this week. According to multiple media reports, Arpaio will be joining him on the trail.

Arpaio has sparked much controversy in supporting and enforcing Arizona’s tough immigration law that allows law enforcement officials to stop and detain anyone suspected of being in the country illegally.

The endorsement from Arpaio could aid Perry with conservative GOP primary voters concerned about his stance on immigration. The Texas governor has stressed his record on border security while campaigning, but has been bludgeoned by conservatives for passing a law in the Lone Star State that provides in-state tuition for undocumented immigrants.

Perry’s GOP rivals, Herman Cain and Michele Bachmann, also sought Arpaio’s endorsement.

Personally, I think it's a little early to be throwing around endorsements before Project White House 2: Electoral Boogaloo kicks off this Thursday, but it's not like Joe Arpaio is exactly known for making wise decisions.
