Y'know, that's the nature of the Presidency, and the whole Executive function.
When you are an elected rep, or a candidate, you can get by on squabbling with the opposition and making a name for yourself in those generally time-wasting process battles.
When you become the HMFIC, you have to make the country work for everyone, not just one party. If Obama had ever held a governorship, he might have had a slight clue about this.
Of course I apologize in advance for my unforgivable racism in daring to mention this...
