Donald Trump may be winning converts from an unlikely source — Democrats — a new unpublished poll shows.What's more, according to the poll, Trump is tied with Hillary — and in fact, the Republican candidate is within striking distance in several historically Democratic states.Sources I interviewed said the poll was conducted by the Harper Polling Firm for the U.S. Senate campaign of GOP State Rep. Dan Carter.The as-yet published poll shows Trump tied with Clinton — each with 43 percent — in heavily Democratic Connecticut.The last time a Republican nominee for president carried Connecticut’s electoral votes was in 1988, when the GOP ticket was headed by George H.W. Bush. The Nutmeg State last sent a Republican to the Senate in 1982 and today has no Republicans in any statewide elected office or any of the five U.S. House seats.Although the Carter campaign has so far not released the poll, its existence is well-known in state political circles and has been discussed increasingly.Conducted between July 5-6 among 600 likely voters statewide, the survey found some surprising results regarding Democratic Sen. Richard Blumenthal: as to whether voters wanted to see him re-elected, 42 percent wanted to see him re-elected and 44 percent said no.Some observers have suggested that Trump himself set the stage for his unusually strong position in Connecticut by early wooing of Democratic and independent voters to help him win the state’s presidential primary. As the Hartford Courant reported on April 16: “From Jan. 1, through the middle of last week, 66,324 new voters have registered in Connecticut: 30,815 as Democrats and 14,355 as Republicans. During that same time period, 13,722 unaffiliated voters joined the Democratic Party while 8,232 became members of the GOP."Trump won the Connecticut primary with 57.9 percent of the vote, and swept all of its 28 delegates.Attending the Platform Committee of the Republican National Convention in Cleveland, Ohio, Connecticut GOP National Committeewoman Patricia Longo told Newsmax: “When you recall how many people changed parties and how easily Mr. Trump won our primary, you understand why his appeal to blue-collar voters and average Americans is changing the landscape in our state.”On its website, Harper advertises itself as “the only Republican polling firm to accurately predict the outcome of the Massachusetts U. S. Senate special election of Senator Ed Markey in June 2013,” and recalls how “we precisely forecasted the 11% margin of victory for Cory Booker in the New Jersey U.S. Senate special election in October 20 [of 2013].”
