Kamala Harris faces her 'toughest' battleground in Pennsylvania

Pennsylvania is the only battleground state where a woman has never won a race for president, governor or senator, nor has a woman been appointed to such a position.

Democrats and Republicans have dumped more advertising dollars into Pennsylvania than any other battleground state, underscoring its importance.

Democrats have spent $114 million statewide this year , Republicans have $102 million .

Pennsylvania is a top priority for the Trump campaign, too, though its in-state footprint is not as large as Harris ’.

The Trump campaign has pointed to her past positions on fracking and immigration as areas where it wanted to expend particular energy in defining Harris .

“ Biden had a legitimate connection to Pennsylvania ,” a senior Trump campaign adviser and Pennsylvania native said.

Pennsylvania Republicans said they were thrilled she did not pick Shapiro to be her running mate.

Shapiro has publicly praised the Walz selection and hinted in his statement that he may have had some misgivings about taking the role.

Some Republicans here said they wanted to see a sharper focus from Trump on the core issues they think will get him and other Republicans across the finish line.
