ABC News is reporting that the Biden campaign is polling how Kamala Harris matches up against President Trump.

The sources that gave them this information says it’s because Trump has begun attacking Kamala:

President Joe Biden’s campaign is testing head-to-head matchups of Vice President Kamala Harris against former President Donald Trump, a source familiar with the strategy told ABC News. It’s a strategic shift that comes with increasing scrutiny on whether Biden should end his 2024 reelection campaign.

The source casts this as a response to the fact that Trump has begun to attack Harris in his public statements and speeches.

“Donald Trump shifted his stump speech. We’d be dumb not to adjust,” the source told ABC News. “We obviously pay close attention to what he is saying.”

That sounds like an excuse to see how Kamala would actually match up against Trump if she were at the top of the ticket. She’s the only real option they have considering that she’s the only one who could be gifted all the fundraising Biden has racked up on the campaign trail.

I wonder if Biden knows they are doing this polling…
