Following the "This Week" roundtable today, we asked our roundtable participants to expand on their discussion. Donna Brazile: Secret Service Scandal Should Not Bring Partisan Witch-Hunt Like most taxpayers, I am appalled by the Secret Service scandal. These are supposed to be the best of the best, the people who would, literally, take a bullet for the president. When they travel abroad, they are not supposed to be "the ugly Americans." We all have frailties, but when they succumb to theirs so flagrantly, it raises the question of "who guards the guardians." As a Democrat, I'm concerned that with the scandals in the Secret Service and the GSA, there will be more of a sense that the government consists of self-serving individuals, not servants of the common good. The Republicans are so anxious to tie the Secret Service scandal to President Obama, they're off on an erotic fishing expedition. There is some degree of scandal in every administration, but what matters is that we have a prompt, fair, rigorous investigation and correction. And that's what we have. This can't turn into a partisan witch-hunt of "who is sleeping with whom." Where will it stop? Matthew Dowd: On Lowering Gas Prices, Honesty Is The Best Policy A part of the conversation on today's "This Week" roundtable asked what a president can do to lower gas prices. Everyone on both sides of the aisle has ideas and answers on what can be done. But the real answer is that a president and the federal government can't do much to lower gas prices â or even to create jobs, which is an even bigger issue. We have had candidate after candidate tell the American public year in and year out that they can solve their issues or fix some problem, whether it is gas prices or anything else. When the problem isn't fixed, the leader either says we need to do more, or that the opposing party is at fault for blocking their solution. The end result is that Americans lose more faith and trust in leaders for making a promise with few results. So instead of making more promises, leaders should be more forthcoming with the public about what they can actually achieve. Begin to restore the trust of the public by speaking frankly and directly. What can a president do? The most powerful thing a leader can do is to help restore confidence in their own leadership, and potentially impact the American psyche in a positive way. Motivate the country, not by policy solutions or legislation, but by telling us the truth and then conveying a vision to get us to where we all want to go. Not some dream of the Garden of Eden, but a place where things aren't perfect but we can have a better life. And it is time for our leaders to tell each of us that the only real way to change the world is to change our own world individually first. If a president started showing us that by his own words and behavior â beginning with direct honesty â then maybe it will give us the strength in our own lives to make the changes we need to make.
