If Trump doesn't win Pennsylvania, there's no real clear path for him to win, and the signs are looking like he won't. Am I wrong?

Title plus - I've been keeping a close eye on Pennsylvania from RCP and 538, early voting / registration, internal polling "leaks", even the subreddit and anecdotal interviews from MSM. It seems like Kamala is trending very well, but I'm pretty terrified that if she loses Pennsylvania, she loses the presidency. Anything can happen on election day of course, but is it just hopium?
