This is short sighted since political parties are both playing for the same team: they are owned by finance and corporations. These are entities that are absolutely not going to allow the radical changes needed to stay within 2c temperature gain (which is still bad, millions will die, but maybe not catastrophic for the species as a whole). Alas, 2c is already priced in given current policies, we will be lucky to stay below 3c. The societal changes from that alone will be devastating.
