The president can when the senate is not in session appoint justices to vacancies in the court who can serve until the end of the next senate session.

Also look at how the new deal and the courts work and how rosevelt manipulated the courts into not declaring the new deal unconstitutional. It is a tacos mating piece of political brinkmanship.

You are understating the power the president has if they wanted to manipulate the court into fitting their biases.

Not to mention if Hillary wins the presidency there is a good chance that the senate will go democrat. This would allow stacking the court quite easily.
