WASHINGTON -- There are many reasons why Sen. John McCain has become the presumptive Republican presidential nominee, reasons that have effectively stymied all of his opponents.
He's been around the nominating track before, remaining at the center of party policy debates ever since 2000, and now it's his turn. He has been out front on the central national security issues of our time, radical Islamic terrorism and the Iraq war. No one has fought wasteful, pork-barrel spending and other big expenditures with more tenacity (he opposed the prescription drug bill) -- a bedrock issue that strongly resonates with his party's base.
These and a few other reasons (like weak opponents) are why McCain has been able to wage a comeback from the brink of political extinction and close in on the 1,191 delegate votes needed to become his party's nominee.
Perhaps none is more important than his previous run for president and his ability to dominate the policy spotlight. He has been a ubiquitous presence on the Sunday morning talk shows for the past decade, maintaining a visibility that his remaining rivals never had. Pollsters will tell you that high name recognition, most other things being equal, is the most valuable political commodity any candidate can possess.
Having run a presidential campaign before does help enormously. Nixon won on his second try, so did Reagan and George H. W. Bush. It may be exaggerated, but the GOP does seem to have a habit of taking turns.
Then there is the dark side of McCain that has enraged conservative talk radio hosts (who have mounted a nonstop offensive against him) and many foot soldiers in the conservative base of his party, a number of whom say they could never vote for him under any circumstances.
We don't know how many fall into that category, but most of them live in Republican red states, like Utah, Colorado, Georgia and Tennessee, that Huckabee and Romney (before it was reported he was dropping out) have been winning (more than a dozen at last count).
Conservatives' differences with McCain are not inconsequential and have been enumerated in this column many times. The senator's opposition to the Bush tax cuts, a First Amendment-bashing campaign-finance bill, his resistance to drilling for oil in ANWR, and the immigration reform bill he supported with Ted Kennedy are all problem areas.
McCain says he now supports the tax cuts and would cut taxes further. He promises to appoint judges to the Supreme Court in the mold of Roberts and Alito. He says he would get much tougher on border enforcement. He acknowledges the campaign-reform bill hasn't worked the way he hoped it would.
