Obama Democrats: Do any GOPers have the right stuff to win?

Story highlights

  • Dan Pfeiffer: GOP faces an uphill battle in the Electoral College and most of its leading candidates seem ill-suited to overcoming that
  • He says Rubio may be best positioned to challenge the Democratic candidate but so far voter enthusiasm for him seems slight

Dan Pfeiffer is a former senior adviser to President Barack Obama and served in the White House in a variety of roles, including communications director. The opinions expressed in this commentary are his.

    Being a little better, a little defter and having a few less vulnerabilities will not be enough to return a Republican to the White House.
    Given those facts, this is a summary based on various conversations, text chains, emails and tweets over the last many months of how the Democrats that elected Barack Obama twice think about the leading Republican candidates (in no particular order):

    Donald Trump

    The biggest task for the Democratic nominee is turning out the "Obama Coalition" of Latinos, young voters, African Americans and women. Thanks to his inflammatory rhetoric and misogynistic statements, Trump would go a long way to accomplishing that goal all on his own. A
