When will McCain answer the "divided Republicans" question

One of John McCain's biggest rivals for the Republican presidential nomination, Congressman Ron Paul, just formalized his rejection of the McCain/Palin ticket in favor of the Constitution Party's presidential campaign of Chuck Baldwin.

Congressman Paul was earning up to 25% of the votes of Republican primary-goers in the second half of the campaign (after McCain clinched it). That's a lot of unhappy conservatives!

After Senator Clinton held an event in Unity, New Hampshire and aggressively and enthusiastically endorsed Obama -- along with every single one of the other Democratic candidates -- isn't it time for some stories on how the Republican/conservative base is more divided than the Democratic base?

A Republican Member of Congress and second-tier but not inconsequential Republican presidential candidate rejecting the Republican nominee in favor of a third party is a rather big deal.
