Worst "President", maybe.
Worst "politician" is not something you can attribute to Obama if the measurement is winning.
The man served two terms as President and won both popular and electoral college vote both times. Call him what you will, but similar to Bill Clinton, the man knew how to win and in that respect he was a good politician.
It’s a basic theory of management that a bad plan well-executed beats the best plan poorly executed.
Obama’s biggest problem was that he was just too lazy and risk averse to execute ANYTHING. This was destined to fail, even if the plan had been outstanding.
No he didn’t winning a election is not the job of politics. Winning the election is a job interview.
Name one thing Obama accomplished by creating even the most basic monocum of support for... just one. In 8 years. He rammed through things that were disasters when his party had control of Congress and accomplished nothing else period.
Even Trump has gotten both parties on board for things in his 3 years even with the democrats openly playing opposition to almost anything he does
And for the record, his re election would have never happened has republicans actually ran for the office. Obama has the distinction of being thr only President in history to be re elected for a second term with fewer votes than he got in his initial election.
It’s actually pretty easy to win elections when your opponents have no intention of winning and throws them to you.
