President Obama, after kicking off the new Congress by issuing a record number of veto threats, faces a growing risk of being isolated politically for saying “no” to virtually every proposal pushed by his Republican opponents.

It’s a new era for a president who vetoed just two bills in his first six years. Obama has unleashed nearly a dozen veto threats in the last month alone. With Republicans now in control of the Senate, Obama doesn’t have the luxury of the chamber’s majority leader keeping bills from his desk.
