One thing you should know about the senate is that they kinda run stuff, for the president. Obama has done or has tried to do all he could to make changes to america. And to repeal thus change, they all(democrats and republicans) have to come together and agree on it. The presidents aims towards financial aid, health care, and providing jobs, the republicans in the senate vote against his plans. Which isnt obamas fault. Id always vote democrat because they care about americans needs and struggles unlike the selfish bully republicans who only wants more riches and want to set out the middle class and the poor out to dry. If anyone, just vote democrat.
Yes, things would have been different. Each president and presidential candidate has different ideas about what he or she would do to help our country. If we had different presidents, they would have done different things when they were in office.
