The National Republican Senatorial Committee (NRSC) on Monday and Tuesday released new attack ads against former Vice President Joe BidenJoe BidenBiden bemoans white supremacy in remarks at civil rights movement site Gun control: Campaigning vs. legislating Sunday shows - Guns dominate after Democratic debate MORE and Sens.

The ads against Warren ask Facebook users who they would vote for between Trump and the Massachusetts Democrat, showing a fluctuating bar graph between the two.

The ads against Sanders say the self-avowed Democratic Socialist would work to “undo all the great work President Trump has done if he becomes president” and “turn America into a socialist country.” 

Going after Biden, the NRSC also asks voters who they would pick between Trump and the former vice president and says a “vote for Joe Biden is a vote for four years of Obama’s leftist policies.”

Biden has sought to tie himself to former President Obama during his campaign, hoping Obama's lingering popularity among the Democratic base will help propel the former vice president to the party’s 2020 nomination. But Obama served as a chief boogeyman for the GOP during his eight years in office. 

The ads against the three Democrats come as polling shows them extending their leads over the rest of the pack, with Sen.

Biden has maintained a narrowing lead among the top three candidates as Sanders has remained largely steady and Warren, buoyed by her litany of detailed policy platforms, has surged in national and statewide surveys.

Several reports have said that Trump and his campaign view Biden as their toughest potential opponent, fearing the centrist former vice president could chip into Trump’s appeal to blue-collar workers in key Rust Belt states that helped hand him the White House in 2016.
