Rep. Alexandria Ocasio-Cortez on Monday took aim at her former rival, Joe Crowley, in an email to supporters that presented the Democratic Senate primary in Massachusetts between incumbent Ed Markey and challenger Rep. Joe Kennedy III as an unlikely battle between their party\u0026#039;s progressive and establishment wings.\u0026nbsp;\u0022It\u0026#039;s not about primaries for the sake of primaries. It\u0026#039;s about the *policy.*\u0022—Emma Vigeland,\u0026nbsp;The Young Turks\u0022While Ed Markey is fighting for the Green New Deal in the Senate, Joe Kennedy is getting campaign support from Crowley hosting a high-dollar fundraiser on October 15th,\u0022 Ocasio-Cortez\u0026#039;s team wrote in an appeal for donations that would be split between her and Markey.\u0022Joe Kennedy thinks that with the backing of the establishment and the old guard of the Democratic Party that he can beat a progressive champion for justice,\u0022 Ocasio-Cortez added. \u0022Let\u0026#039;s show Kennedy that he\u0026#039;s wrong.\u0022\u0026nbsp;Amazing.Team @AOC sends out a scathing email blast about Joe Kennedy\u0026#039;s big money fundraisers on behalf of Green New Deal co-author Ed Markey.See, establishment types? It\u0026#039;s not about primaries for the sake of primaries. It\u0026#039;s about the *policy.* Not that hard to grasp! pic.twitter.com/BDAzxvDffq— Emma Vigeland (@EmmaVigeland) October 7, 2019Crowley, the New York Democrat who lost a primary election to Ocasio-Cortez in 2018, is listed as a \u0022host\u0022 for an October 15 fundraiser for Kennedy hosted by lobbyist Tracey Spicer.The event, according to reporting from\u0026nbsp;The Boston Globe, asks attendees from different tiers to donate to the the Kennedy effort to depose Markey:According to the invitation, hosts for the fund-raiser are asked to give $5,600 to Kennedy\u0026#039;s campaign—the maximum amount an individual can give for the primary and general election, combined. The invitation asks \u0022co-hosts\u0022 to pony up $2,800, \u0022supporters\u0022 to give $1,000; and \u0022friends\u0022 to contribute $500.The timing of Crowley\u0026#039;s insertion into the race comes weeks after Ocasio-Cortez endorsed Markey, her Senate co-sponsor for the Green New Deal.\u0026nbsp;A Kennedy campaign official, speaking on background, told\u0026nbsp;Common Dreams that Crowley and Kennedy\u0026#039;s friendship is longstanding and that Crowley\u0026#039;s presence in the race has nothing to do with Ocasio-Cortez.\u0022They are genuinely close friends and have been for a long time,\u0022 said the campaign official.As\u0026nbsp;Sludge\u0026nbsp;pointed out on October 4, Crowley\u0026#039;s post-Congress career has set him up nicely to raise cash and wield influence:Crowley is not just the guy whom AOC beat; he is now senior policy advisor at Squire Patton Boggs, a powerful D.C. lobbying firm that represents large corporations such as oil company Royal Dutch Shell, Management and Training Corp.—the third largest private prison company in the U.S.—and insurer UnitedHealth Group.The juxtaposition of Ocasio-Cortez, the political upstart whose primary challenge upset the national political order, endorsing the incumbent Markey with her establishment opponent backing Kennedy, who is running on a message of change, was not lost on Boston-based political activist Jonathan Cohn.\u0026nbsp;\u0022Some pundits have drawn comparisons to Ayanna Pressley\u0026#039;s challenge to Mike Capuano last year, with Kennedy invoking rhetoric akin to Pressley\u0026#039;s \u0026#039;Change can\u0026#039;t wait,\u0026#039;\u0022 said Cohn. \u0022But the dynamics of the race are very different.\u0022Joe Crowley hosting fundraiser for Joe Kennedy. ....Meanwhile, AOC has endorsed Markey.https://t.co/gbVuSlL7D1— Sarah Ferris (@sarahnferris) October 3, 2019The\u0026nbsp;Globe\u0026#039;s reporting appears to bear out that perception of the race\u0026#039;s dynamics.The paper gave a rundown of a who\u0026#039;s who expected at the October 15 fundraiser:Former (Ted) Kennedy\u0026nbsp;staffers\u0026nbsp;listed on the invitation include Stephanie Cutter, who went on to serve in the Obama administration and as deputy campaign manager for President Obama\u0026#039;s 2012 reelection campaign, among other roles; David Bowen, who served as staff director for the Senate Committee on Health, Education, Labor, and Pensions when the elder Kennedy was its chairman, and played a major role in drafting and steering the Affordable Care Act through the Senate; and Tom Lopach, a former executive director of the Democratic Senatorial Campaign Committee who is currently working on Montana Governor Steve Bullock\u0026#039;s presidential campaign.In her email to supporters, Ocasio-Cortez said that the stakes for the Massachusetts primary are clear.\u0022We need to help keep Markey in the Senate where he has a proven record of fighting for transformative change,\u0022 said Ocasio-Cortez.
