Team McCain returns to traditional economic themes in their latest ad, “Dome”. They hit Barack Obama as being a traditional, doctrinaire liberal who will spend hundreds of billions of dollars and expand federal government — at our expense:

When our economy’s in crisis, a big government casts a big shadow on us all.

Obama and his liberal Congressional allies want a massive government, billions in spending increases, wasteful pork.

And, we would pay — painful income taxes, skyrocketing taxes on life savings, electricity and home heating oil.

Can your family afford that?

The McCain campaign has succeeded in driving this message. In most polling, Obama has lost most of his lead on economic matters, the biggest issue on the minds of voters this year. John McCain has attacked Obama’s strength and succeeded, while Obama has spent most of his time attacking Sarah Palin.

I’m surprised that the McCain campaign didn’t cut an ad about McCain’s attempt to reform Fannie Mae and Freddie Mac in 2005/6 and point out Obama’s inaction on the bill. Maybe that’s coming later, but now is the time to hit that point — while it remains fresh in the minds of the voters.
