There’ll be at least a few friendly faces:

WASHINGTON (Reuters) – When Democrats gather in Denver next week to nominate Barack Obama for president, they’ll be joined by such uninvited guests as Republicans Rudy Giuliani and Mitt Romney. The two former presidential candidates will be among two dozen or so Republicans in the city hoping to get their party’s message out during a week dominated by Democratic festivities. Their slogan? “Not Ready ‘08: A Mile High and an Inch Deep,” a play on the nickname for the high-altitude city in the western United States. Republican presidential candidate John McCain, Obama’s rival for the November 4 election, is expected to keep a relatively low profile that week, though he is scheduled to appear as a guest on “The Tonight Show” talk show on Monday. His surrogates will set up shop within walking distance of the Democrats’ convention hall, hoping to catch the attention of the 15,000 reporters gathered there.

A warning, however. Running the phrase “A Mile High and an Inch Deep” through the Bob-Herbert-a-tron gives a 72 percent chance of being misinterpreted as a phallic, racist attack.
