As I write this answer, Barack Obama is the president. But on November 6th, 2012, there will be an election. We do not know who will win it, but after it is over, we will know if Mr. Obama is re-elected or if Mr. Romney is the new president.
Mitt Romney has never been a president.
Mitt Romney hasn't been president so we can't answer that yet.
Mitt Romney is way more wealthy that President Barrack Obama in personal savings.
On November 6, 2012, Barack Obama defeated Mitt Romney, and was re-elected to the presidency. Thus, Barack Obama remains the president.
