Since Vice President Kamala Harris seized the Democrat spotlight, she's received a tsunami of grassroots support and cash, two-thirds of it from first-time donors.

At the same time, former President Donald Trump, who rallied supporters in Tennessee and Minnesota this weekend, is carving out new lines of attack in a reshaped campaign.

CBS's Skylar Henry leads us off tonight from the White House.

Skylar, good evening to you.

Hey, Jerika, good evening to you.

The Harris campaign says it's raised more than $200 million since President Biden's sudden exit from the race, the enthusiasm also prompting her Republican rival to escalate his attacks.

She's a radical left lunatic.

Former President Trump took aim at his presumed political opponent Saturday in front of a packed arena in St.

Cloud, Minnesota.

Kamala Harris's deadly destruction of America's borders is completely and totally disqualifying for her to be president.

She's evil.

It was a 180 from the calls for national unity by Trump after his attempted assassination just two weeks ago.

At the same time, Trump's VP pick, Ohio Senator J.D.

Vance, is facing closer scrutiny following past comments including criticizing childless Americans in political leadership.

No, you should never say anything to hurt anybody's feelings.

But when you look at all these interviews by J.D., he was talking about how the Democratic party has abandoned the traditional family.

Potential Harris running mates slammed the rhetoric and are punching back.

It's exactly why Donald Trump's attacks aren't going to work.

I mean, two nights ago, he called her a bum.

If he wants to see a bum, he ought to look in the mirror.

If he has laughed, it's at someone, not with someone.

That is weird behavior.

As the vice president rallies support across the country, voter enthusiasm in both parties has skyrocketed.

We don't take anything for granted.

That's why we're supporting Donald Trump as much as we are.

This is the big push to get him across the finish line to save America.

I feel energized.

I feel excited.

I think we're going to do it.

We beat Donald Trump the first time.

I think we can do it a second time.

A new poll out today shows in the last week, Vice President Harris saw an 8% boost in favorability among Americans at 43%, compared to former President Trump, whose favorability dropped to 36%.

On another topic, CBS News has learned President Biden is expected to unveil his proposals to reform the U.S.

Supreme Court during a speech tomorrow in Texas.

That plan would include introducing term limits and a code of ethics for justices, both of which would likely require congressional support.

All right, so much happening.

Skyler, thank you.
