A lot of us are skeptical of your conservative bona fides. Your past voting record has not given a lot of conservatives hope that you are the man to (1) beat Obama in November and (2) if you do win that you will follow through when you take the oath before God to uphold the Constitution.

Many conservatives have given up on the Republican Party. Who can blame them? The song from The Who comes to mind: “We won’t be fooled again.”

I’m sure you realize that you were not the first choice of many who voted in the primaries. While there are some holding out that there will be a political savior to replace you before the November election, I don’t believe it’s going to happen. With the support you are now getting, you better come through. Words, rhetoric, and promises are not enough.

Your candidacy brings to mind the 1998 film Saving Private Ryan. I’m sure you’ve seen it, but let me remind you of the movie’s storyline. At the War Department in Washington, General George Marshall is informed that three of four brothers in the Ryan family have died within days of each other and that their mother will receive all three telegrams notifying her of their deaths on the same day.

General Marshall learns that the fourth son, Private First Class James Francis Ryan is missing in action somewhere in Normandy. Marshall orders that Ryan be found and sent home immediately because of the Sole Survivor Policy.

A special group of soldiers have a singular mission. Find Private Ryan and bring him safely home. After intense fighting and loss of life among their group, the remaining squad members, led by John H. Miller (Tom Hanks), locate Private Ryan. There’s one more battle to be fought. While the battle is won Captain Miller is gravely wounded. Ryan is with Miller as he dies. Miller’s last words haunt Ryan for the rest of his life: “James . . . earn this. Earn it.”

Your poll numbers are up. More conservative and independent voters are getting on board. I was glad to see that you’ve come out against homosexual marriage. Will you stick with this view or will you also “evolve”?

Will government shrink on your watch? How often will you use the veto pen? Take a lesson from Gov. Scott Walker. He stood up against his political opposition, won the day, took the heat, and is facing a recall election. He has not given in. He’s earning the respect of the state.

I sat next to Gov. Walker at a fund raising dinner that was put together to help him beat back the recall effort in Wisconsin. He was resolute. He did not waver in his convictions as he spoke to us.

His steadfastness is paying off. It was painful for him, his family, and the Republican Party, but he knew that his decision would save the state. He was attacked on all sides, and he still didn’t bend.

Mr. Romney, a lot of people are counting on you. Millions of reluctant voters are going to give you a chance. Don’t disappoint them. Earn it. The future of America is at stake.
