Donald Trump, the President Without a Party

Estrangement from Republican leaders clouds the White House’s agenda

With virtually no Republican votes to spare in the Senate, where his agenda hangs in the balance, he has nonetheless become estranged from two key figures in his own party. First it was John McCain of Arizona, over his defiance of the president on health care. Next it was Bob Corker of Tennessee
.. Mr. McCain is chairman of the Senate Armed Services Committee; Mr. Corker is chairman of the Senate Foreign Relations Committee. Thus, the president is alienated from the two most important Senate figures on national security at a time when two critical national-security issues are coming to a boil: the fate of the nuclear deal with Iran and the increasingly dangerous standoff with North Korea.
.. “Bannon’s current obsession is to blow up Senate Majority Leader Mitch McConnell and Republican Senate incumbents whom he regards as hostile to his brand of nationalism.”
..  Mr. Trump would like to lead, and Mr. Bannon would like to create, a Republican Party different from the one that exists. It would be a party molded in the Trump image: nationalist, skeptical of immigration and trade agreements, dubious about the virtues of diplomacy and international negotiations, with economic strategies skewed to help workers in traditional American industries.
.. wants the GOP to be the party “of the American worker.”
.. The current version of the GOP was built largely by merging the interests of the business community with the agenda of social conservatives. Neither of those groups would win top billing in the vision for a new, Trump-inspired party.
..  it isn’t at all clear that such a new Republican Party would, in fact, be a majority party. 
.. The current party has just 52 members in the Senate, and, as noted, Mr. Trump doesn’t have the loyal support of all of them. Mr. Bannon and his allies are threatening to challenge other Republican incumbents in primary elections next year, which won’t exactly keep those targeted at his side.
