Really? How's staying on message about the economy been working so far?
If you feel that would fail, then you know nothing about politics. If you did, you would know you don't dwell on opponents attacks, you use them to your advantage to point out positive aspects about yourself, then re-direct the attack back at them.
Here's further
"If you want to vote for the two clowns doing prop comedy, go right ahead. This isn't last comic standing, this is a race for the presidency. It's serious business. Something I know a lot about. I'm out here talking about my experience as a successful businessman who has created jobs, and my fiscally conservative record as Governor, blancing the budget without raising taxes, and how I can use that experience to turn the country around. I guess when you don't have any leadership experience, you're left to twist statements and make jokes. Perhaps that's why they're trailing so bad in this race -- they aren't talking about what the people are really concerned about -- the economy. There were some appauling numbers just released by Obama's own administration, about how the debt has grown faster under this president than any other, and a serious budget proposal submitted by Paul Ryan which has the kind of sharp cuts in spending we need in Washington. Instead of backing the proposal, my oponents are out there playing with kids toys and making jokes. There's a lot of people out there taking a serious at how to get us out of this mess. They need to get serious, theres some tough business ahead. Frankly, with the lack of focus on the important issues, you have to wonder if they're even qualified for it."
If they continue to push about the comment, you add;
"Listen, when Eric was asked about troubles with getting Republican support in certain areas of the country, and he was right to point out these results will change when we start over in the general election, where Im certain I will get the full backing of conservatives against a wreckless spending liberal like Obama. But, we are staying focused on the real issues, and how to move America forward, and achieve our goal of getting Obama out of office, so we can get the economy growing, get big government out of people's lives, get the money back in the hands of the people, and repeal ObamaCare."
