Bush hits '08 trail to rev up his party

US President George W. Bush has made it clear he is excited to get out on the campaign trail this election year to help Republicans keep the White House and retake Congress - but do they want his help?

Republican presidential hopeful John McCain has said he wants help from Bush, who can haul in enormous campaign cash. But McCain has walked a fine line with the unpopular Bush, backing the president on the Iraq war while bucking him on how to address climate change.

Bush was to kick off raising money for McCain yestersday and today at three events in Arizona and Utah, but they will only be together at one and it will be out of the public eye. That has raised questions about whether Bush helps or hurts the Arizona senator.
