It's that they have that much money, especially for media buys.
There are literally hundreds of millions of dollars being dumped into the Republican state campaigns as well as Romney's. Spin we expect. But the level of outright lying is stunning.
If our billionaires succeed in this, first, we are likely to have another 2008 style Crash without the money to bridge over it. Second, we will be on an historic path, crony capitalism and plutocracy, that leads to outright failure. If Romney wants a bigger military and more wars as he says, I'd like to know where the boots and the money are to come from. Even cutting US life expectancy by at least 5 years as Paul Ryan wants to do wouldn't pay for it all..
The billionaires and Romney have offshore accounts and helipads.
