From an email I received. I live close to WV but not in WV:
"Manchin ONLY votes correctly when is afraid of losing and being at only 35% if he takes this vote will make him TERRIFIED. Give $5, $10, $25, $50, or more to defeat Biden's Supreme Court nominee NOW! Our pressure STOPPED Joe Manchin from voting for the Build Back Better Agenda, and we can do it AGAIN! But we cannot do it without YOUR help, we aren't funded by George Soros or tech billionaires in San Francisco. We rely on grassroots supporters like you!"
Here's the link if you want to give them some money. I know, it's winred. https://secure.winred.com/westvirginiagop/poll-memo-cs
Why on earth would it be too late? I've seen longtime incumbents defeated time and again when they ticked off their voters enough to have them toss them out. What MAGA candidate did you support against him?
