in any meaningful way. He's their "ace in the hole" if they can't stop Trump or Cruz.
Remember what's at stake for the RW power brokers.
Yes, the White House, but the question then becomes why. My theory? Three reasons (from the Koch Bros' and KKKarl Rove's p.o.v.).
1) COAT TAILS. Republicans are faced with defending 24 seats in the Senate this presidential year, 18 which are competitive. They need to maintain power in Congress order to block any policy that may benefit the American people and/or disadvantage rampant corporate greed. An eventual Democratic president with "coat tails" ruins those plans. So a strong Democratic front-runner - one who is actually fund-raising for Democrats down the ballot - cannot win.
2) SCOTUS. A Democratic president filling Scalia's empty seat - and a Senate under Democratic Party control advising and consenting, will turn the political leanings of this hyper-partisan SCOTUS more to the left. Citizens United? GONE. Section 4 of the Voting Rights Act? Reinstated (no more egregious voter suppression/poll taxing for historically racist States). Also, three more SCOTUS seats are rumored to open up within the next eight years (Ruth Bader-Ginsberg, Stephen Breyer, and Kennedy - and, if President Obama can't get Chief Judge Garland through, the next president will. I believe, though, that with Hillary as our nominee, she'll most likely show President Obama the respect he's due {and has rarely gotten} and push Chief Judge Garland through to the SCOTUS. Then she still has three more justices to appoint in her two terms.
3) REPUBLICANS FEAR HILLARY CLINTON. She knows where the bodies are buried and which closets Republican are hiding their skeletons, and she's known for going head-to-head with any obstructionist Republican to get things done. She's a strong ally and friend, but when crossed, becomes a formidable opponent who plays to win.
Their best bet is to get a clueless Socialist to win the Democratic nomination, and they can't do that if they showed the country how useless this congresscritter has been in the past, ergo, no meaningful vetting allowed.
