Having Clinton on the ticket would switch the VP and P debates from the USA economy to world affairs. Though Romney might have some moxie about foreign affairs (and would be well served to get a person with such experience including military on board and out front) I don’t believe Romney would get much help from Ryan when it comes to Hillary.
"It's the economy, stupid."
People vote with their wallets. Ryan can run rings around hillary when it comes to domestic issues. I think Americans would put America first.
Hillary, like her husband, would want to raise taxes like her husband, but Bill had Reaganomics to cover for the revenue loss. All Hillary has is Obomanomics, so there's no money left to cover up the losses. Oboma has already lost us 5 trillion. We can't afford a tax increase this time.
