A day before the Democratic National Convention, the Harris-Walz campaign is planning a bus tour in western Pennsylvania. Vice President Kamala Harris and Minnesota Gov. Tim Walz, along with their spouses, will begin the tour in Pittsburgh. Harris holds a narrow lead over former president Donald Trump in the presidential election, according to a Washington Post-ABC News-Ipsos poll released Sunday. That’s a notable improvement for Democrats in a contest that showed President Joe Biden and Trump in a dead heat a little more than a month ago. The Republican vice-presidential nominee, JD Vance, is appearing on “Fox News Sunday,” one day after Trump held a rally in Wilkes-Barre, Pa.
