Barack Obama
In light of the fact a new Congress is forming, with newbies going through orientation, U.S. President Barack Obama, will have to change his political strategy, due to the losses his party sustained. The luxury of ramming through legislation is gone, making the rest of his presidency a challenging one.
Will Obama adapt or will he fight against Republicans, rather than compromise. There are politicians in the President's party harboring anger over the midterm elections, blaming it on the fact they supported his agenda and voters penalized them for it, by withdrawing their support. It will be a struggle for him to win back many in his party as well, lamenting the loss of their Congressional majority.
