While the Republicans are gathering in St. Paul for their national convention to confirm the candidacy of Senator John McCain as presiden,t and Governor Sarah Palin as his running mate, Turner Classic Movies is presenting a night of alternative politics.

The cable channel going to present five movies about politics, and if you want to see how the world of running for public office has changed in the 20th century, these films are a fantastic reflection of the times.

On Wednesday, September 3, starting at 8 PM ET, the night begins with The Last Hurrah, and includes The Candidate (10:15 PM), The Best Man (12:15 AM), Nashville (2 AM) and The Dark Horse (1932).

Like I said, these pictures are all really interesting choices. The Candidate, released in 1972, for instance, is not so different from today's campaign pitting Senator Barack Obama versus Senator John McCain.

It's a young candidate espousing change, up against an experienced, wizened establishment candidate. Robert Redford plays Bill McKay, the up and comer, while Don Porter is the popular, long-time incumbent senator. Check out these photos, because Porter even looks like McCain!
