    Republicans trail Democrats by 7 percentage points on the    generic congressional ballot, according to a new    POLITICO/Morning Consult poll, the Democratic Party's greatest    advantage on the generic ballot since the poll began asking the    question this past spring.  
    The survey, conducted last Thursday through Saturday, shows a    generic Democrat leading a generic Republican, 44 percent to 37    percent, with 19 percent of registered voters undecided. The    two parties were tied, 40 percent apiece, in the previous    weeks poll.

    The results came on the heels of a week in which the GOP effort    to repeal Obamacare crashed and burned in the Senate and    President Donald Trumps chief of staff left the White House    abruptly.

    Democrats previous high-water mark on the generic ballot    question  which asks voters which party they would support in    a congressional election without mentioning specific candidate    names  had been a 6-point lead in early May.  
    Democratic voters back the Democratic candidate by an    almost-unanimous margin, 90 percent to 2 percent. Republicans    are slightly less unified, supporting the GOP candidate, 85    percent to 5 percent. Among independents, the Democrat leads,    34 percent to 25 percent, with 41 percent undecided.  
    Even as the GOP slumped on the generic ballot, Trumps approval    ratings held fairly steady over the past week. In the new poll,    42 percent of voters approve of the job he is doing as    president, while 53 percent disapprove. Last week, 43 percent    of voters approved of Trump, and 52 percent disapproved.  
    Still, the long-term trend for Trump has been downward  and it    has the potential to drag down Republicans in elections this    year and into the 2018 midterms.  
    "In our poll taken immediately following President Trump's    inauguration, 31 percent of independent voters disapproved of    him," said Morning Consult Co-founder and Chief Research    Officer Kyle Dropp. "In this latest poll, that number has    nearly doubled to 56 percent. What's more, the percentage of    voters who 'strongly' disapprove has jumped from 23 percent to    41 percent in that same time period."  
    That slide connects to the GOPs electoral prospects. Among    voters who strongly approve of Trump in the new poll, 79    percent of them prefer the Republican congressional candidate,    while 8 percent would vote for the Democrat. By contrast, 80    percent of voters who strongly disapprove of Trump would vote    for the Democrat, and 8 percent would back the Republican.  
    The problem for Republicans: While 41 percent of the electorate    strongly disapproves of Trump, far fewer, only 22 percent,    strongly approve of his job performance.  
    Intensity isn't the only worry for the GOP: There is the basic    fact that more voters disapprove of the job Trump is doing than    approve. In the POLITICO/Morning Consult poll, 71 percent of    voters who approve of Trump's job performance even somewhat    would vote for the Republican candidate, compared to 72 percent    of those who disapprove who are backing the Democrat.  
    The new POLITICO/Morning Consult poll was conducted during a    tumultuous close to the week for Trump and his party. The poll    was already in the field early Friday morning, when the Senate    voted down the latest GOP bill to repeal parts of the 2010    Affordable Care Act. Similarly, some interviews had already    been conducted when Trump announced that he was replacing Chief    of Staff Reince Priebus with John Kelly, the now-former    secretary of homeland security.  
    Previously released poll results show a    majority of voters believe the Trump White House is running    chaotically, even before some of the most recent turnover.  
    The poll was fielded after Trump sharply criticized Attorney    General Jeff Sessions in public comments and on Twitter. A    53-percent majority of voters say Trumps statement that he    would not have appointed Sessions if he knew the then-senator    would later recuse himself from the investigation into Russian    meddling in the 2016 election is inappropriate; only 27 percent    say Trumps comments are appropriate.  
    In another controversial statement last week, Trump announced    on Twitter that the U.S. would not accept or allow    transgender individuals to serve in the military, though any    transgender ban has yet to take effect. Voters generally    disagree with Trump: By a 68 percent to 21 percent margin,    voters believe the U.S. should allow transgender members of the    military to continue serving. And 55 percent say the military    should allow transgender individuals to join, while only 31    percent say they should be barred from joining.  
    Sixty-seven percent of voters do say, however, that the    military shouldnt pay for gender-transition expenses, compared    to only 21 percent who think the military should pay for that    treatment. Trump cited tremendous medical costs for    transgender personnel in explaining his decision.  
    The poll surveyed 1,972 registered voters and has a margin of    error of plus or minus 2 percentage points.
