Actually, many new GOP senators will be pretty darned establishment

“When you have folks like Portman and Blunt who have been in leadership and understand that being in the Senate is more than obstruction, it makes the Senate a better place,” said Janet Mullins Grissom, a former McConnell chief of staff who lobbies at the bipartisan firm Johnson, Madigan, Peck & Boland.

The list of established political veterans goes on: former Sen. Dan Coats of Indiana, New Hampshire Attorney General Kelly Ayotte and, depending on election outcomes on Nov. 2, as many as four more House hands — former Rep. Pat Toomey (R-Pa.) and Reps. John Boozman (R-Ark.), Jerry Moran (R-Kan.) and Rep. Mark Kirk (R-Ill.) —- who have experience inside the Beltway.

Indeed, it’s easy to see Portman negotiating on budget and trade matters, Blunt acting as a liaison to his former House colleagues, Hoeven working on issues that affect state budgets and Rubio being a key Republican voice on immigration policy. Coats, who served as the U.S. ambassador under Bush, worked with Democrats such as Vice President Joe Biden and the late Ted Kennedy (D-Mass.) on various issues during his decade in the Senate.
