Some hope that the GOP takeover of the House will cause the two parties to work together to get things done. But some political analysts are warning of the opposite — that Congress will become even more polarized. One reason is that most of the Democratic incumbents who lost were fiscal conservatives from Republican-leaning districts. That means that the Democrats who are left in Congress are more liberal. And based on how some of their colleagues were punished in GOP primaries for seeking bipartisan solutions, remaining moderate Republican lawmakers may be less likely to make deals with Democrats.
