In the last few days, Biden’s campaign has taken a few shots at his rival’s campaign for a raise.
In a recent video, Biden called on his supporters to take the fight to Hillary Clinton, who Biden has called a “fraud” in the race for the White House.
“We’re going to do everything we can to win,” Biden says in the video.
The video has since been taken down.
At the same time, the Biden campaign has been promoting a series of paid media ad spots that target Clinton supporters.
On Wednesday, Biden campaign chairman David Plouffe tweeted that the ad campaign would continue to spend heavily in battleground states, including Michigan and Ohio.
But the campaign has also taken to social media to try to tie its ads to its primary opponents.
One ad features a group of people with a camera holding signs that say, “Biden, I support you.
We need you.”
Another shows people wearing “Bidens” shirts.
Biden’s campaign also has begun airing robocalls to supporters in battlegrounds, hoping to tap into a larger part of the Democratic base that has traditionally voted for Clinton.
Meanwhile, a Biden spokesman says that the campaign is planning to air a series and will spend about $4 million on television ads in Ohio and Florida.
