Trump meeting with Sen GOP goes about as well as you'd expect

[Mr. Morden]

To be President, you've got to support your Presidential nominee.  Period.  I cannot think of a single Governor or Senator whose career took off AFTER they dissed their party's Presidential nominee.

Plenty of members of Congress have no intention of ever running for president, and are only interested in holding onto their current jobs for as long as possible.  So I'm not sure why this calculation should be an issue for them.

I'll agree with that to an extent.  Not supporting your party's nominee is, however, something that will hinder a Congressman should he desire to become a committee chairman, or even a subcommittee chairman.  It would certainly preclude a chairman getting a seat on a major committed like Rules, Ways and Means, or Armed Services, where even subcommittee MEMBERS have more power than a big shot on, say, the House Administration committee.

This didn't matter prior to 1974, when both parties went by strict seniority.  Then, in the aftermath of the 1974 elections, the Democratic Caucus, led by Rep. Phil Burton (D-CA), voted three (3) senior committee chairmen out of their chairmanships.  Those three were Rep. Wright Patman (D-TX) chair of the Banking committee, Rep. W. R. Poage (D-TX), chair of the Agriculture committee, and Rep. F. Edward Hebert (D-LA), chair of the Armed Services committee.  Hebert did not support McGovern.  Poage did, but he was pretty silent about it, and had a super-conservative record, as did Hebert.  Patman was an old-time populist, but his record was conservative and hawkish, and there were rumors of senility.  It wasn't all about McGovern, but it was all about being a "national Democrat", and the GOP followed suit to where now, party regularity is requires.  Arlen Specters and Chris Shayses aren't just going to get chairmanships by keeping office and keeping breathing.

Now there's a difference here.  Trump is the presumptive nominee, but he's out of tune with the GOP caucus on a number of issues.  That's different than McGovern, who was more liberal than folks wanted, but he was the liberal nominee of the more liberal party.  Trump isn't quite a liberal, but he isn't a conservative as Republicans have defined the term.  Still, there's a risk in not supporting your party's nominee, even if it's Trump.  

The thing is, Ryan and McConnell have both given green lights to their caucuses to bolt. 

Yep.  The idea that anyone in Congress is going to be punished with bad committee assignments for not supporting Trump is ridiculous.  No one will even care about Trump anymore by next January, when the new Congress is convening.
