The unlikely alliance between Donald Trump and Big Tech

Why is President Donald Trump putting so much energy into defending Silicon Valley — not his most natural constituency — through US trade policy? President Trump is treading a politically delicate path as he tries to help Big Tech improve its access to foreign markets at a time when the sector is increasingly becoming a punching bag in Washington. In a hypothetical 2020 contest against Sen Elizabeth Warren (D-MA), the Democratic presidential candidate who has called for a break-up of the US tech giants, President  Trump could be vulnerable to attacks that he has been excessively friendly towards the companies. Criticism could mount from the right as well. Many conservatives mistrust Big Tech for allegedly censoring their views.
