I think there are lots of reasons to oppose Sen. John McCain’s candidacy for the presidency. He’s too bellicose, too interventionist to be entirely to my liking. Libertarians (and Republican activists) don’t like him because of his sponsorship of the McCain-Feingold campaign finance reforms. Some conservatives don’t like him because of his support for comprehensive immigration reform (although he’s been making a slow transition to their preferred enforcement-first policy). Some Democrats are portraying a McCain Administration as a third George W. Bush term (which I think is an exaggeration).
One of the very worst reasons to oppose him is the idea that he’s too darned old to be president. I really don’t think that one can be made to stick or, more precisely, if it is made to stick it will have some unforeseen secondary effects.
The third in line for the presidential succession according to the provisions of the Presidential Succession Act of 1947 is Nancy Pelosi, Speaker of the House of Representatives. Speaker Pelosi is 68. Too old?
The fourth in line for the presidential succession is Sen. Robert Byrd, president pro tempore of the Senate. If Sen. McCain who would be 73 on the day of his hypothetical inauguration is too old for the presidency, at 91 Sen. Robert Byrd certainly is.
The clear implication is that Speakers of the House or Presidents pro tem of the Senate can’t be too old, either. However old that is.
The idea would also restrict Sen. Obama in his choice of running mate or cabinet appointees.
