Sen. Thad Cochran (R-Miss.) can use as much help as he can get right now. Even if that help comes from some odd places.

Former New York City Mayor Michael Bloomberg, who has devoted most of his political capital to gun control efforts, and former Facebook president and creator of Napster, Sean Parker, who is a generous donor to mostly Democrats, each donated a quarter of a million dollars to the super PAC backing Cochran’s re-election.

Henry Barbour, nephew of Haley Barbour, the former Mississippi governor, runs Mississippi Conservatives. The PAC reported $1.28 million in contributions from mid-May through June 4.

Barbour told the Loop Friday he did not want to speak for Bloomberg or Parker, but surmised that although they disagree on many issues “they’re giving because they see [Cochran] is not an extremist like Chris McDaniel.”

Cochran is fighting for his political life as he faces a runoff primary against McDaniel, the tea party’s pick. The stakes are even higher after outgoing Majority Leader Eric Cantor’s primary loss rocked political conventional wisdom this week.

A spokesman for Bloomberg declined comment. Parker, for his part, just formed a new group to promote political activism by “re-energiz(ing) interest in democracy by bringing together people who are passionate about different issues …”

Perhaps he is leading by example?
