Who wanted war?

 A couple of days ago, Christopher Caldwell wrote "Republicans trusted Mr. Trump to take over their stumbling party in large part because he cursed the George W. Bush administration for having led the country into the Iraq war with a bunch of specious talking points about weapons of mass destruction."   Today a New York Times news story said "Mr. Trump won the presidency in 2016 in part by rejecting nation-building and foreign wars."  This seems wrong to me--Trump has always been clear that he has no objection to war as long as it's profitable.  I searched the Trump Twitter Archive through 2016 and found nothing objecting to the original rationales for the wars in Iraq and Afghanistan, but lots of complaints that we were spending money and not getting Iraqi oil.  

A Pew survey in September 2015 asked Republicans about a hypothetical candidate for the party's nomination who "wants to send US ground troops to fight ISIS in Iraq and Syria."  Among people who favored Trump, 56% said they would be more likely to support such a candidate and 26% that they would be more likely to oppose one; among people who favored someone else, it was 52% more likely to support and 26% more likely to oppose (the rest said it wouldn't make much difference to them).  That is, opinions about sending ground troops to fight ISIS were unrelated to Republican candidate preference.  

This question was part of a series.  Two of the other items--"wants to end the nuclear agreement with Iran" and "will compromise with members of the Democratic Party" were also unrelated to the choice between Trump and other candidates.   Three others were related.  One was "wants to deport all immigrants living in the US illegally."   Among Trump supporters, 51% said they would be more likely to support such a candidate and 18% that they'd be more likely to oppose; among supporters of other candidates, it was 36% and 39%.  Another was "wants to end federal funding for Planned Parenthood."  Among Trump supporters, 42% more likely to support and 27% less likely; among supporters of other candidates, it was 57% to 20%.  Finally, on "wants to raise taxes on wealthy Americans," 44% of Trump supporters said they would be more likely to support and 24% to oppose; among supporters of other candidates, it was 30% to support and 39% oppose.  That is, Trump supporters were more in favor of a hard line on immigration, but more moderate on Planned Parenthood and taxes on wealthy people.

It's often said that Trump has achieved a takeover, sometimes even a "hostile takeover," of the Republican party.  But it's actually gone in both directions:  he's moved the party towards his position on some issues (especially immigration and tariffs) but has adopted orthodox Republican positions on others where he once seemed to be more moderate (taxes, abortion, "our always under siege Second Amendment").  Between his first and second terms, Trump also has taken up some previously fringe positions on the right, like unbridled hostility to colleges and universities, and introduced them into the mainstream.
