By CNN's Jack Cafferty:
Mitt Romney went "bold"... doing what many conservatives wanted him to do in naming Paul Ryan as his running mate.
Many view the Ryan pick as a game-changing one, with both Republicans and Democrats cheering Romney's choice.
But it's yet to be seen if Ryan will make voters more - or less - likely to vote for Romney.
Ryan's weaknesses are pretty evident. His budget plan of drastic spending cuts includes significant changes to Social Security and Medicare. Try selling that to elderly voters in Florida.
It also gives Democrats ammunition to play on those same voters' fears, that the social programs they rely on could be threatened.
Plus, Ryan has virtually no experience in the private sector - just like President Obama. He has spent almost 14 years in Congress - a career politician at a time when America is sick of Washington.
But - Romney's selection of Ryan also carries plenty of benefits.
For starters, while voters are sick of Washington insiders, they tend to reward politicians who push for real change... see Barack Obama in 2008 or New Jersey's Chris Christie.
For Americans who grasp the critical nature of our skyrocketing national debt... now nearing $16 trillion... Ryan has a lot of appeal.
And if Mitt Romney is willing to embrace even some of Ryan's ideas... Pres. Obama won't be able to touch the GOP on government spending and deficits.
Ryan is also a clear plus for the party's base, many of whom have never really liked Romney. He appeals to crucial independent voters, Catholics and women too.
Most importantly, the choice of Ryan signals a clear choice for voters in November. More government versus less government. Runaway national debt versus painful fiscal responsibility. Ryan is a big gamble for Mitt Romney - but it's a bet he almost had to make.
Here's my question to you: How much will Paul Ryan help Mitt Romney's chances of winning?
