Well Burgum brings money, once he's the officially the VP nominee he could dump as much as he wants into the campaign, right?
Yes, assuming he is ready to spend a lot of that money. It would certainly help. However, I think Trump's main focus right now is electability, not funding - if he is elected all his troubles go away (i.e. he pardons himself). That is why I think that (through gritted teeth) he will pick Haley or, at the very least, go with a woman VP candidate like Stefanik, to soften his image with suburban women voters.
Trump isn't gonna soften his touch with females Females vote D 60/40 in blue states where in red states they vote more R, obviously, because they are stuck in low wage jobs like minorities, Trump tax cuts that give oil subsidies to oil companies will do no bridge between rich and poor
