President Donald Trump has been a target of many campaign attacks. On Wednesday, former Vice President Joe Biden became one too.
During his speech in Phoenix Tuesday, President Trump seemed to telegraph a Biden attack ad that began running in Phoenix Wednesday. "You know who's lost it? Sleepy Joe has lost it."
The ad titled "Has Biden lost his mind?" is produced by the Committee to Defend the President. By editing together a series of verbal flubs that Biden has made, the ad asks if the former Vice President suffers from dementia.
Republican strategist Stan Barnes says whatever you think of the ad, it hits hard. "The Biden ad is particularly effective because Joe Biden is 77 years old, because he does have some real moments when it's a legitimate question about what is going on in that head of his."
Democratic strategist Luis Acosta thinks the ad is effective but does not believe it will have a lasting impact.
"President Trump is having to make up a lot of ground locally and nationally," Acosta says. "So while this could move the needle, I just don't see it moving the needle in a significant way."

President Trump's mental and physical fitness have also been the subject of a stinging political ad.
Some parts of the country have seen a campaign spot produced by the Lincoln Project which uses unflattering video of the President and asks if there is something wrong with his health.
Barnes says what was once considered historically outrageous, is just another day in the 2020 presidential campaign.
"Both are going to exploit and so it might just even out. What I think of as mutually assured political destruction."
