Maybe the lack of a Spanish-American War might influence that?
Certainly could in Teddy's case, as no Spanish War means no San Juan Hill, so probably no NY governorship or Vice-Presidency.
Thoufh what other changes could happen, such as no US control in the Philippines or Guam.
They might be bought out by the Germans - or just grabbed by the Japanese. The latter (if Japan still joins the Entente in 1914) could make America friendlier to the CPs - though probably not to the point of joining them.
