Where do you draw the line? From CNN...
WASHINGTON (CNN) — Sen. Joe Lieberman, a Democrat turned Independent, will endorse Republican Sen. John McCain for president, officials close to both Lieberman and McCain familiar with the plan tell CNN.
An aide to Lieberman tells CNN he decided to endorse McCain because he considers him "the most capable to be commander in chief on day one of his administration, and the most capable of uniting the country so that we can prevail against Islamic extremism."
The Lieberman aide insists the senator does not see this as a "commentary on or an endorsement of the Republican party, only the person."
Lieberman will continue to caucus with the Democrats.
"Until when" is the question on my mind.
