While Trump and Ryan engaged in a cordial meeting last week, Ryan hasn't endorsed Trump. The meeting was a move to create unity within the Republican Party after a tumultuous primary season.
Trump will need the support of all Republican groups to win in the general election and party unity is an important step to victory. Some have speculated that Ryan will eventually endorse Trump, especially if Trump gives him some reassurances on his policy positions.
The question of party unity often has been examined within the context of ideology. Early on in the primaries, Trump did less well with very conservative voters. Interestingly, very conservative voters show a higher level of trust for Trump over Ryan.
Sixty-three percent of Republicans who identify as very conservative said they trust Trump more than Ryan to lead the Republican Party. Only 34 percent of very conservatives trust Ryan over Trump. Conservatives also trust Trump over Ryan but the margin is narrowed from 29 points among very conservatives to 17 points among conservatives — 57 percent to 40 percent. Moderates favor Trump over Ryan by the same margin as conservatives.
