Vance went to college to be a lawyer. He can be smooth at times, then can be an absolute idiot at others. He has had more missteps than I can count. Right now what are the biggest issues for the Trump/Vance campaign - The dog/cats - that was pushed initially by Vance. Cat ladies, as those that don't have kids. Again issue pushed by Vance. That he cannot admit Trump lost the election. These are all on Vance. Then of course abortion and January 6th.
You can talk about missteps by Walz, but he has nothing compared to those by Vance. They didn't really go after his misstatements on his military record, seems like that was nothing they could really get him on. Now appears maybe they will go after China ties.
Of the 2, though the biggest hits will still be on the Trump/Vance side, especially with Trump unwilling to do another debate. Will be interesting if the polls begin to converge or continue to sway Kamala's way.
