    Progressive groups will mount a multi-phase effort against    President Donald Trumps Supreme Court nominee, targeting    specific Democratic and GOP senators and preparing a broader    assault on Republicans to pressure them against blowing up the    filibuster  even as some Senate Democrats pledged Monday to    block Trumps pick.  
    Leaders of key groups have been meeting privately to coordinate    strategy for the past month, and have already begun to talk    protest plans in senators home states and at the Supreme Court    in Washington, with early conversations about fundraising and    advertising underway.

    They are still outraged by the Republican blockade of Barack    Obamas nomination of Merrick Garland last year but are trying    to cast their own opposition as different  particularly as    Trump already has issued a series of executive orders that have    prompted court challenges nationwide.  
    Foremost is Trumps far-reaching and controversial executive    order to ban immigrants from several predominantly Muslim    nations, a directive sure to be a focus in the coming Supreme    Court fight.  
    There is now an urgency to oppose anyone who wont be a    powerful check on the Supreme Court against the executive    branch excesses and impulses, said Nan Aron, founder and    president of the Alliance for Justice. I would predict that    there will be a huge outcry if the nominee cannot demonstrate    that he or she could be independent and serve as the check on    presidential power.  
    On the Democratic side, progressives are zeroing in on    red-state Democrats like West Virginias Joe Manchin and North    Dakotas Heidi Heitkamp. Among Republicans, theyre looking at    Arizonas Jeff Flake and Nevadas Dean Heller, who are both up    for reelection in 2018, and the moderate Susan Collins of    Maine.  
    And while conservative forces are already putting the finishing    touches on a $10 million ad blitz targeting red-state Senate    Democrats who will come under enormous pressure to back Trumps    nominee, People for the American Way is readying a television    ad campaign of its own as a counterbalance.  
    There will be resources available to make the case, said    Marge Baker, the groups executive vice president. This is a    fight that were going to be in, in an absolutely serious way.  
    The advocates contend they have both the progressive energy to    pressure Democrats to hold the line, and enough of a buffer in    a Democratic caucus of 48 members to lose several while still    being able to block a nominee.  
    There is a lot of energy in the progressive space to say,    This seat was stolen from a Democratic president, period. It    was grand larceny, said Brad Woodhouse, president of    Americans United for Change. Democrats in the Senate, and    progressives and liberals who care about the unprecedented    nature of that theft by Republicans, shouldnt roll over for    Donald Trump and his Supreme Court pick.  
    Along the way, theyre hoping to drive a major wedge between    Republicans in the Senate, many of whom are wary of blowing up    the filibuster completely, and Trump, whos made clear thats    what he wants if Democrats dont confirm his nominee.  
    I dont advocate taking the same approach that GOPers took to    Garland (in refusing meetings, hearings and votes), said one    former Obama White House official. Id advocate for close,    intense scrutiny at every stage of the process  which I think    will eventually lead just about every Dem to oppose the nominee    and likely at least some GOPers.  
    For months, groups such as the Alliance for Justice and People    for the American Way have done extensive research on the nearly    two dozen judicial candidates whom Trump named during his    campaign, with special focus recently on names that have popped    up more frequently  such as Third U.S. Circuit Court of    Appeals Judge Thomas Hardiman and 10th U.S. Circuit Court of    Appeals Judge Neil Gorsuch, two jurists reportedly at the top    of the pack.  
    The pro-abortion rights group NARAL Pro-Choice America has also    been distributing its own research on where potential nominees    stand.  
    A broad array of liberal groups, including People for the    American Way, The Leadership Conference on Civil and Human    Rights, Alliance for Justice Action Campaign, and Center for    American Progress Action Fund, have organized a protest for    Tuesday night at the steps of the Supreme Court against Trumps    nominee, wholl be announced earlier that evening.  
    Senate Democrats  who are also waging a political fight over    Trumps executive orders and Cabinet nominees  for the most    part have tried to reserve judgment until the president    actually unveils his pick. Democrats have been insisting on a    so-called mainstream nominee, although Minority Leader Chuck    Schumer (D-N.Y.) has conceded that he believes Trump wont pick    such a candidate.  
    Still, Democrats are almost sure to face a massive level of    pressure from the base to hold the line against Trumps pick.  
    They need to fight like hell and do all they can to confirm    only someone who is fair and an independent judge who can serve    as a check to this president, said Ellen Buchman, executive    vice president for field and communications at the Leadership    Conference for Civil Rights.  
    Though the advocacy groups insist they are not simply trying to    go tit for tat over the obstruction of Garland, theres little    doubt that the lingering frustration over how Obamas final    nominee was treated has permeated thinking among many    Democrats.  
    Thats how we see this, one Democratic senator said of the    Garland blockade. The anger, we feel it in our stomach.  
    Whenever the Supreme Court fight begins in earnest, Democrats    wont be hungry for help from the outside.  
    The Constitutional Responsibility Project, organized by former    Obama aides last year to push for Garlands confirmation, will    be reconstituted at the offices of SKDKnickerbocker, with    Sheila OConnell, most recently Chris Van Hollens 2016 Senate    campaign manager, coming on board.  
    The opposition-research group American Bridge is preparing a    full-research, rapid-response and video-tracking operation to    expose the nominee as too conservative and out of step with    mainstream Americans, said Kevin McAlister, a spokesman for    the group.  
    And End Citizens United, a political action committee that    advocates for campaign finance reform, is readying a national    grass-roots campaign that will push its 3 million members to    flood senators with calls, emails and petitions, as well as a    digital advocacy effort, spokesman Adam Bozzi said.  
    All that is to counter the expected assault and pressure from    conservatives, who backed the Senate GOPs nearly yearlong    blockade of Garland but now expect Democrats to fall in line.  
    Schumer said its hard for him to imagine a nominee  from    President Trump who Senate Democrats could support, Senate    Majority Leader Mitch McConnell (R-Ky.) said Monday. We dont    even have one yet. I hope we can get past that and get down to    our serious work.
