Get real. When it comes to The Supremes, a president can urge in one hand and take a dump in the other and see which one fills up first. The only way a president can really influence the court is by being in the presidency when Supremes die or retire (or have the party in power of the Senate refuse to hear any nominees for a year before the election from a president they don't like), so they can pick nominees that have consistently ruled in accordance with what the president picking them wants to see happen, and have party control of the Senate to force them through.
