Honestly, for me it went:
"Hah is he kidding? This might be the most unqualified VP pick ever."->"Oh shit people are buying her 'I'm just like youuuuuuuuuuuuuu!' nonsense; how can this be? Is middle/southern America really this slow?"->"Oh favorable ratings dropping, America waking up, interviews are hilarious spectacles, McCain is hating his staff for forcing him to make this pick now."
And that's where I am currently.
So yes, during the week following the Republican convention, there was a little nervousness there but that's all gone now. Not saying it won't come back if Biden pulls some stupid shit thursday.
