A reader in the Bronx forwarded me an article from The Riverdale Press in which Councilman Oliver Koppell hedges somewhat in whether he’ll primary Independent Democratic Conference Leader Jeff Klein.

While Koppell was critical of Klein coalition alliance with the Senate GOP (“He’s betrayed the Democratic Party,” Koppell told the paper), he wouldn’t commit to a primary.

“It’s a tough race,” Koppell said. “I don’t know if I’m the best candidate to run.”

Nevertheless, Koppell believes Klein should be booted from the Senate and blamed him for the failure in the Legislature to approve an overhaul of campaign finance laws and the passage of the abortion plank in the women’s agenda.

The Koppell skirmish is part of a larger internecine battle between the mainline Democrats and the breakaway conference that formed a governing majority with numerically outnumbered Republican lawmakers.

In another flare up, the IDC has expressed interest in backing former Assemblyman Richard Brodsky in a primary against Senate Minority Leader Andrea Stewart-Cousins.

In an interview on The Capitol Pressroom this morning, Stewart-Cousins told host Susan Arbetter she was “sad and surprised” to learn of the potential Brodsky challenge.

Ever since the Independent Democratic Conference was formed in 2011, threats and counterthreats have been bandied back and forth by either side (much to the delight of Senate Republicans).

So far, the only tangible primary challenge from the IDC aimed at a mainline Democrat has been the ill-fated effort by Shawn Morse, an Albany County legislator, who was crushed by Sen. Neil Breslin last year.

Updated: I’d be remiss to note that as per Arbetter, Brodsky has said he’s not running for Stewart-Cousins’s seat. So, shockingly, this was pretty much an exercise in wheel-spinning.
