Quote:Alexandria Ocasio-Cortez is already making enemies in the House Democratic Caucus — and some of its members are mounting an operation to bring the anti-establishment, democratic socialist with 2.2 million Twitter followers into the fold.

The effort, described by nearly 20 lawmakers and aides, is part carrot, part stick: Some lawmakers with ties to Ocasio-Cortez are hoping to coax her into using her star power to unite Democrats and turn her fire on Republicans. Others simultaneously warn Ocasio-Cortez is destined for a lonely, ineffectual career in Congress if she continues to treat her own party as the enemy.

“I’m sure Ms. Cortez means well, but there’s almost an outstanding rule: Don’t attack your own people,” said Rep. Emanuel Cleaver (D-Mo.). “We just don’t need sniping in our Democratic Caucus.”

Incumbent Democrats are most annoyed by Ocasio-Cortez’s threat to back primary opponents against members of their ranks she deems too moderate. But their frustration goes beyond that: Democratic leaders are upset that she railed against their new set of House rules on Twitter the first week of the new Congress. Rank and file are peeved that there’s a grassroots movement to try to win her a top committee post they feel she doesn’t deserve.

Even some progressives who admire AOC, as she’s nicknamed, told POLITICO that they worry she’s not using her notoriety effectively.

“She needs to decide: Does she want to be an effective legislator or just continue being a Twitter star?” said one House Democrat who’s in lockstep with Ocasio Cortez’s ideology. “There’s a difference between being an activist and a lawmaker in Congress.”

It’s an open question whether Ocasio-Cortez can be checked. She’s barely been in Congress a week and is better known than almost any other House member other than Nancy Pelosi and John Lewis. A media throng follows her every move, and she can command a national audience practically at will.
