Here's an article written by former Reagan adviser Bruce Bartlett;
Imbalanced Budget: Ryan Gives Wealthy A Free Pass

Crunching the Numbers
Ryan got around this problem by ignoring the Joint Committee on Taxation, Congress’s official revenue-estimating agency, and instead asking the ultra-conservative Heritage Foundation to crunch the numbers for him. Its analysis says that economic growth would be so extraordinary from enactment of the Ryan plan that the unemployment rate would fall two full percentage points next year alone, and continue to fall to less than 3 percent by 2020 – a level not seen since 1953. This massively higher growth leads to higher federal revenues – $58 billion more next year alone over those that would be collected without the Ryan plan.
A number of respected public finance economists quickly ridiculed the Heritage numbers as grossly implausible. MIT economist Jonathan Gruber said, “The Heritage numbers are insane.” In response to such criticism, Heritage simply deleted some of the more extravagant figures from its analysis.
Distributionally, the Ryan plan is a monstrosity. The rich would receive huge tax cuts while the social safety net would be shredded to pay for them. Even as an opening bid to begin budget negotiations with the Democrats, the Ryan plan cannot be taken seriously. It is less of a wish list than a fairy tale utterly disconnected from the real world, backed up by make-believe numbers and unreasonable assumptions. Ryan’s plan isn’t even an act of courage; it’s just pandering to the Tea Party. A real act of courage would have been for him to admit, as all serious budget analysts know, that revenues will have to rise well above 19 percent of GDP to stabilize the debt.
Why Ryan
In other words, Ryan threw out a bunch of unrealistic numbers to see if they would stick.
Secondly, how can people trust Ryan based on his history. The man voted for Medicare Part D including making it illegal for the government to negotiate lower pricing from the pharmaceutical companies, this added cost for the taxpayers. The Drug Program's estimated cost equals that of Obamacare.
Secondly, Ryan voted for TARP which doesn't exactly fall into being a spend-thrift.
And NOW he's the champion of the far right? Me thinks somebody is getting fooled.
