Angry Republicans are making ignorant remarks about Barack Obama at campaign rallies, forcing John McCain to defend his opponent. What a sad time for the GOP.

Remember, millions of Americans remain undecided as the presidential race enters its final three weeks.

These voters are watching to see how the candidates conduct themselves -- and who is supporting them.

In the case of McCain and running mate Sarah Palin, there have been embarrassing reports of outlandish comments being hurled around at the rallies.

For instance, one woman told McCain last week that she didn't trust Obama: "I have read about him and he's an Arab."

To his credit, McCain replied, "No ma'am, no ma'am. He's a decent family man ... that I just happen to have disagreements with on fundamental issues."

Over the weekend, Palin stoked a GOP rally in Ohio with these words:

"Help me, Ohio, to help put John McCain in the White House.... We understand how important it is that this team be elected. For one thing, we know who the bad guys are, OK?”

Reporters noted Palin's remarks elicited shouts of "Obama" from some in the crowd.

Later, Palin's clean-up crew said she had been talking about terrorist nations, not Obama. So why not just say that?

Because Palin is the kind of candidate who wanted to leave the impression with her supporters that she was talking about Obama and his backers.
