Democratic pollster Pia Nargundkar said on Monday that Democrats are more likely to focus on issues such as health care and immigration when speaking to voters because they have stronger messaging on those issues.

"I think Democrats are just going to focus on the issues that they feel better about, and that voters are naturally inclined to hear them out about," Nargundkar, a senior associate at ALG Research, told Hill.TV's Jamal Simmons on "What America's Thinking."

"That's why you see people talking about the Green New Deal, and you hear them focusing a lot more on health care and education because that's their natural strong suit, rather than sort of trying to yank and pull voters on this issue that they don't want to be talking about," she continued, referring to Democrats' messaging on border security.

Democratic 2020 hopefuls have recently put their focus on issues largely amplified by the progressive wing of the party, such as "Medicare for all" and the Green New Deal.

However, the issue of border security has played a critical role in the conversation within the Republican Party amid President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE's calls for recent a southern border wall.

Republican and Democratic lawmakers are in the process of attempting to meet a Friday deadline to reach a deal on border security amid Trump's demands for border wall funding.

However, negotiations between the two parties have hit a rough patch over Democrats' desire to to cap the number of beds available to hold detained immigrants.

Trump lashed out at the demand in a tweet on Monday.

"The Democrats do not want us to detain, or send back, criminal aliens! This is a brand new demand. Crazy!" Trump tweeted.
