According to the polls and the pundits, Mitt Romney and Newt Gingrich are the two front-runners for the Republican nomination for president. That means both of them will spend the next few weeks trying to show that they are more competent, conservative and generally Reagan-like than the other.

But as a uniter, not a divider, I don't want to focus on the differences between Romney and Gingrich. I want to focus on the commonalities. Because these two men have a lot in common with each other and with President Barack Obama.

Both Gingrich and Romney, for instance, supported a universal health care plan backed by an individual mandate requiring all Americans of means to purchase health-care insurance — just as Obama does.
