In case you wondering what happened to Paul Ryan:

Despite his Wisconsin record of defeating unions and overcoming a recall election, some Iowa conservatives now find Mr. Walker overly supportive of his own party’s Washington leadership, at least compared with Mr. Trump, who delights in dismissing elected officials collectively as “stupid.”

“Where he’s really messed up with people like me,” said Phil Cavanaugh, a Republican chairman in Wapello County, who was once a Walker supporter, “is that he keeps bringing up his buddy-buddy relationship with establishment people like Paul Ryan.”

(Mr. Ryan, the Wisconsin congressman, is chairman of the House Ways and Means Committee, who some grass-roots Republicans say has broken with conservative principles.) Mr. Walker seems to have heard this message. On the conference call with donors, he promised to remind voters that he had to take on fellow Republicans to push his agenda through in Wisconsin. And on conservative talk radio and at the state fair this week, he took aim at Senator Mitch McConnell of Kentucky, the majority leader.
