United States Politics
Since 2009, the president is a Democrat, so Democrats have slightly more power in the federal government. However, there are still many powerful Republicans who can try to stop the Democrats from doing things that they believe will be bad for the country. Also, the Democrats do not always agree with each other on what to do. And if enough people decide to vote against Democrats in the next election, then they will lose power. In a republic like the United States, no party can do whatever they want. All politicians have to argue, compromise, and make deals with each other to get things done. They have to answer to the people and take responsibility for their mistakes.
