Donald Trump’s admiration of Russian President Vladimir Putin isn’t a good look generally, but it may play particularly badly with Americans of Eastern European descent … and it turns out there are a lot of them in some key battleground states.

In Pennsylvania, according to the most recent Census data available, there are more than 100,000 people of Ukrainian descent; 820,000 of Polish descent (a demographic that tends to lean more Democratic but that cares about strong support for NATO); 46,000 Croatians; and thousands of Lithuanians, Latvians, Albanians, Estonians and people of other Eastern European ethnicities. In Ohio, there are around 40,000 Ukrainians, more than 400,000 Poles, and thousands of Americans of other Eastern European heritage.

Although these groups tend to vote Republican, there may be an opening for Hillary Clinton this year:

“The Latvians are primarily Republicans, as are Lithuanians, Estonians, and many Ukrainians, but Trump has put them in a real bind,” said Maris Mantenieks, a Latvian leader in Ohio’s Eastern European ethnic community. “Because in all honesty they don’t want to vote for [Clinton], and yet again they can’t express their Republicanism due to Trump’s positions.” These voters, many of whom live in swing states like Ohio and Pennsylvania, are deeply worried by an emboldened Moscow, and anxious over the possibility that the Baltic nations might be the next target of Russian adventurism. Trump’s lavish praise of Putin has exacerbated those concerns — leaving an opening that Clinton’s campaign is leveraging by emphasizing her willingness to get tough with Putin, and her unwavering support for NATO. Earlier this month, Clinton met with Ukrainian President Petro Poroshenko in New York — and her allies made sure to publicize the message that Trump snubbed him.

And in states like Ohio, relatively small numbers of defections from traditionally Republican voters could make a big difference.
