Majority of voters think Kamala Harris is responsible for the border crisis, higher levels of inflation, and Afghanistan exit

The Trump campaign has sought to tie Kamala Harris to the border crisis, three years of inflation, and the disastrous withdrawal from Afghanistan.

Her own campaign has tried to link her to controlling drug prices and economic growth.

Both efforts seem to be working, according to a J.L. Partners/DailyMail.com which found high proportions of voters blamed her or credited her for a slew of policies implemented during her time as Joe Biden's vice president.

In particular, 60 percent of likely voters said was very or somewhat responsible for the record number of crossings at the southern border.

The Trump campaign sees that as a winning issue. 

It has called her the 'border czar' and claimed that she was put in charge of immigration policy.

In fact, she was tasked with working with central American countries to tackle the root causes of the problem, encouraging people not to head north by promoting economic development, for example, and creating, jobs.

Yet the poll suggests the idea she had a bigger role has stuck. 

Some 55 percent also say she was to blame for high levels of inflation.

And 49 percent believe she was very or somewhat responsible for the departure from Afghanistan, which triggered Biden's first major crisis in office, with the deaths of 13 U.S. service personnel. 

She later said she was the last person in the room when the decision was taken.

On the other hand, 45 percent associate her with significant economic growth, the same proportion that say she was not responsible. 

But 53 percent do credit her with work to cap drug prices. 

James Johnson, co-founder of J.L. Partners, said the results illustrated where she might be vulnerable.

'Voters think Harris is responsible for more of the bad things that have happened under Biden than the good,' he said. 

'That suggests the attack line—that we heard in Trump's closing statement at the debate in response to her plans, "why didn’t you do any of this"—will be effective. 

'Given VPs don't have much power, and historically don't have much impact on anything at all, that is an achievement the Trump campaign will be pleased with—especially in an election where voters want change from the status quo.'

The Trump campaign has been on the back foot since Biden sensationally dropped out of the race, elevating Harris to the top of the ticket.

She has enjoyed a polling and fundraising bonanza.

This week she moved into the lead in the J.L. Partners/DailyMail.com poll but by just a single point.

The result is a race that is still far too close to call.
