McCain junket tied to presidential bid?

McCain heads overseas to observe global warming effects - The Business Journal of Phoenix: :
"Sens. Lindsey Graham, R-S.C., Mel Martinez, R-Fla., Saxby Chambliss, R-Ga., Richard Burr, R-N.C., and John Sununu, R-N.H., are slated to go on the congressional trip with McCain."

The newspaper is too polite to make the connection explicit, but includes this helpful list of key states:
"The Arizonan is expected to run for president again in 2008 and is courting voters and key GOP supporters in battleground states such as Iowa, Florida, Ohio, South Carolina, New Hampshire and California."

Of the six states on that list, three have Republican senators traveling in McCain's group (FL, SC, NH) and one has no GOP senator (CA). Of course, this is merely a coincidence. Also merely coincidental is that, if McCain is to do well in SC, he should be looking to do well in NC and GA, as well.
