8. Dave Brat (R-Va.). Brat, a Randolph-Macon College economics professor, delivered perhaps the biggest political upset of the year when he toppled former House Majority Leader Eric Cantor (R-Va.) in the June GOP primary. His victory came partly by accusing Cantor of being “pro-amnesty” on immigration. Brat has also declined to say whether he’ll support Boehner for Speaker.
