So what does Google Trends - which monitors the pulse of American's interest through its search, say about these topics?
Do American's searches suggest that they're more interested in a good or bad economy?
As you can see above, "bad economy" peaked during the Great Recession. Since about 2012, sentiment has decidedly turned towards "good economy." It's even stronger than it was pre-recession.
What about illegal immigration? Trump has said that before he came along this issue was largely ignored.
As you can see, the peak mention of illegal immigration was about April of 2006. Since then it has largely faded in terms of the number of searches. Not really an issue new to Trump and certainly not bigger in the minds of Americans since his campaign began.
Finally, what about crime? Even cops are being shot. Surely people are upset about this?
Crime searches are higher than they were just a year ago. Curiously, they are still lower than they were in February 20011 and considerably lower than November 2005.
It is not just public perceptions as measured through this window of searches that suggests these hot buttons Trump is pushing are not that hot. Illegal immigration, unemployment, and even the number of police officers shot is down from what it was in previous administrations. Reality and perception alike indicate that these aren't big issues for Americans.
Donald is certainly pushing buttons. It's not obvious that they're wired into the country's collective anxieties.
Ted Cruz tells convention attendees to "Vote your conscience," and gets booed off the stage.
Trump and Pence stand on stage at the convention's close with their families to sound of Rolling Stones playing, "You Can't Always Get What You Want."
