I don't see big difference between Dent and Costello, except on abortion issue (where i, naturally, prefer pro-choice position)
Costello is probably one of the twenty-five most moderate Republicans in the House, whereas Dent is probably in the top three(along with Ileana Ros-Lehtinehen and Richard Hanna).
Dold has to be more liberal than IRL, as does Freilinghuysen. I know Dold is retiring. In my opinion, if one is not pro-life, they are not a Republican or a conservative.
Bullsh*t. Governors Baker and Scott, Senator Collins and dozens state legislators come to mind immediately. Plus - hundreds former Republican politicians of very high caliber. Right-wing idiocy.
Two terrible people and mediocre Senator...great examples!
