Answer 1

Taft was less progressive than they had hoped.

Roosevelt and his supporters felt Taft abandoned progressive priorities (e.g., he signed the conservative Payne–Aldrich Tariff, fired Gifford Pinchot in the Ballinger–Pinchot affair, and aligned with party conservatives), causing the 1912 split.
