Is Arizona In Play?

Two new polls would lead one to believe McCain is in trouble at home:

Cronkite/Eight:
McCain 46%
Obama 44%

Zimmerman:
McCain 44%
Obama 42%

These numbers may force McCain to make a detour in the last week of the campaign, from defending states Bush won in 2004 to defending his own turf. To be sure, I don't expect Obama to win Arizona's 10 electoral votes next week. But if McCain doesn't make an appearance there between now and Election Day, things may get pretty tight. And if there is some overwhelming Obama tidal wave of unexpected proportions, then all bets are off.
