Republican front-runner Donald Trump’s presidential primary victories apparently are causing some voters to look into insurgent moves to block the real estate mogul from the White House. The search term “how to stop Trump” has cropped up in corners of the United States — some, more than others.

In the last week, Massachusetts had the highest rate of searches, followed by Washington, Connecticut and Virginia. Trump emerged on top of the Massachusetts and Virginia Republican primaries March 1, winning 49.3 percent and 34.7 percent of the vote, respectively, in the Super Tuesday states.

The win likely prompted the Google search “how to stop Trump” to trend. In Washington and Connecticut, the opposition movement inquiries appear to be pre-emptive measures. Washington will not hold its Republican caucus until May 24, while Connecticut is preparing for its April 26 primary.

Regional Google search trends showed Michigan with the highest incidence of “how to stop Trump” inquiries Tuesday, the same day voters head to the state's primaries.

Trump is expected to win Michigan, where he leads in most polls. Political site FiveThirtyEight predicted that Trump has a 92 percent chance of victory in the state. In a new Monmouth University poll, the real estate mogul had the support of 36 percent of likely Michigan Republican primary voters, with Texas Sen. Ted Cruz behind at 23 percent and Ohio Gov. John Kasich in third with 21 percent. Florida Sen. Marco Rubio had 13 percent of support in Michigan. 

Alabama and Washington lagged behind Washington in terms of interest in the last 24 hours. Mississippi and Idaho also have primaries Tuesday, but the search was not trending in either state. Internationally, the Google search has peaked this month, as Trump saw success in early Republican contests.

Google searches surged for “how can I move to Canada” after Trump swept the Super Tuesday primaries. The search saw a spike of 2,450 percent since Trump won more primary elections last week, according to the Huffington Post.

Toronto's government officials have tweeted information on how to move to Canada in response.
