Business mogul Donald Trump is known for amassing wealth. Now, he’s amassing more of an increasingly hot commodity: Republican votes in New York.

A Siena College poll released Monday morning shows Trump surging in the primary matchup six weeks ahead of the day when New Yorkers will cast their primary ballots. The Manhattanite is pulling in 45 percent of the vote among GOPers. The next closest candidates are Marco Rubio and John Kasich, whose own surge has propelled him to 18 percent of the vote from 4 percent last month.

On the Democratic side, the numbers for Hillary Clinton and Bernie Sanders didn’t budge from February. Clinton leads 55-34 among Democrats.

That Trump jumped another 11 points in the Republican primary matchup — in which only four candidates remain — isn’t a shock given his sustained success nationally. The Siena poll was conducted in the midst of Super Tuesday last week, during which Trump won seven of 11 states in play. On Super Saturday last weekend, Trump won two of four states in play.

Trump (and Kasich) also seems to have benefited from Jeb Bush and Chris Christie, who is now allying with Trump, dropping out of the race in the past month. Those two Republicans were pulling in 7 percent and 11 percent of the vote, respectively, in Siena’s February poll.

“A quarter of the electorate had to go somewhere,” Siena College pollster Steven Greenberg said.

Yet for all of Trump’s success in the primary matchup, New Yorkers of all parties seem to have trouble liking the guy. Trump’s favorable-unfavorable numbers among all voters are at 29-67. Though they aren’t far off what Rubio and Ted Cruz pull in, all three are being outpaced by Kasich on that question. The Ohio governor has a positive 41-29 favorable-unfavorable rating.

Among the independents who have helped Trump succeed in states with open primaries (New York’s primaries are closed; in other words, only members of the Republican Party can vote in the GOP primary), Trump has a 32-64 favorable-unfavorable rating.

Kasich outpaces his three GOP opponents among that subset of voters, scoring a 48-27 favorable-unfavorable rating.

Trump does best among Republicans, 54 percent of whom view him favorably (that’s 2 percent lower than Kasich’s favorable rating). Even then, 33 percent of Republican voters say he’s the candidate they would least like to see be the Republican nominee heading into November.

Upstate, Trump, the self-proclaimed “most popular person that’s ever lived” (EVER!), is viewed unfavorably by 65 of residents regardless of party (his 31 percent favorability does outpace Cruz and Rubio, though). And yet, he still wins the four-main Republican matchup with 44 percent of the vote.

Trump has painted himself as having a strong chance of winning New York not just on April 19, but also in November.

Siena shows data to the contrary.

Clinton continues to win all head-to-head Democrat-Republican matchups. Sanders also wins against the four GOPers.

The introduction of former New York City Mayor Michael Bloomberg as a third-party candidate doesn’t change Clinton’s success in a matchup against Trump. Both Clinton’s and Trump’s numbers dip, but the former New York senator still emerges victorious with 42 percent of the vote to Trump’s 25 percent and Bloomberg’s 26 percent.

Even with a Trump surge and Sanders consistently eating up a large chunk of the vote, it still is not a shocker that Clinton does well in her home state.

“Bernie does well with young Democrats, as we’ve seen across the country …,” Greenberg said of the Democratic primary. “But Hillary does very well with the older voters, and they are the more reliable voters.”

Of Sanders’ steady 34 percent of the vote in the primary matchup, Greenberg said that describing the Vermont senator as having plateaued isn’t quite they way he would put it.

“New York Democrats know and really like Hillary Clinton and are very comfortable with Clinton,” he said.
